 +For stage-scanning, the value of the calibration slope only matters if you want the value of the offset as measured in microns to match the physical world.  Normally you can just leave it at its default value.
  
 Generally the calibration slope will remain relatively constant but the offset can change slightly. It is easy to update the offset without changing the slope (e.g. when introducing a new sample): Generally the calibration slope will remain relatively constant but the offset can change slightly.

 +==== Simultaneous Cameras ====
 +
 +This option was added so that multiple cameras could be used on the same path, e.g. a single-view SPIM with 4 different cameras to record each camera looking at a different spectral window at the same time.
 +
 +Due to Micro-Manager viewer limitations there are some oddities about this feature's implementation.  In simple cases with only 2 cameras it may be easier to instead use the setting on the Settings tab to record from 2 views simultaneously.  When using "Use simultaneous cameras on Path A" each "channel" in the dataset is a different camera as expected.  However if multiple channels are used also, each channel is assigned a portion of the resulting stack, and furthermore no time points are allowed.  For instance with 2 cameras and 3 sets of lasers and 50 slices in the stack the resulting dataset would have 2 channels and 150 slices.

 +==== Simultaneously acquire from both paths/cameras ====
  
 +This option was added to enable reflective imaging where cameras on both sides are triggered together (see https://www.nature.com/articles/s41467-017-01250-8).  Both cameras should be wired to the same trigger signal using e.g. a BNC "tee" at the Tiger controller output.

 +Note this is similar but distinct from the option to acquire multiple cameras on Path A which is configured on the Cameras tab.  However in many cases either one can functionally be used.

 ==== Multiple Positions (XY) ==== ==== Multiple Positions (XY) ====
  
-For large samples there is a YZ grid creator (as of March 2018) so multiple strips can be collected covering a sample. The same GUI allows you to create a “grid” in X where, instead of specifying slice spacing, you specify start and stop positions, and number of slices. If the box is checked, the plugin will use Micro-Manager’s position list to acquire volumes and multiple locations. For each time point, every position is visited once. See Micro-Manager User’s Guide for more details on the [[https://micro-manager.org/wiki/Micro-Manager_User%27s_Guide#Position_List_Dialog|Position List Dialog]].+If the box is checked, the plugin will use Micro-Manager’s position list to acquire volumes and multiple locations. For each time point, every position is visited once (i.e. the positions are an "inner loop" if both positions and time points are used). See Micro-Manager User’s Guide for more details on the [[https://micro-manager.org/wiki/Micro-Manager_User%27s_Guide#Position_List_Dialog|Position List Dialog]]. 
 + 
 +The XYZ grid creator facilitates acquisitions of multiple uniform strips to cover a large sample. Open the grid creator window by clicking on the "XYZ grid..." button.  The window houses a few other related features described below. 
 + 
 +==== Using the Grid Creator ==== 
 + 
 +Select the axes that you want to create the grid in and click the "Compute grid" button to set up the grid.  For thin samples you do not need the Z grid.  You can mark specific start/stop positions in live mode using the corresponding "Set" buttons.  The delta for Y and Z can be entered manually, or if you click the "Set" button next to those fields then the value is populated based on the camera ROI and the overlap percentage setting. 
 + 
 +The X axis is used for stage scanning, so when you create a "grid" in X you are specifying start and stop positions and spacing between them in stage coordinates.  If you enable "Slices from stage coordinates" in the XYZ grid window then the values "slices per side" and "slice step size" in the main acquisition window will be changed based on the settings in the XYZ grid window. 
 + 
 +The button "Compute Grid" will populate the position list with coordinates from the above settings.  This position list is in turn used with the Multiple Positions feature of the plugin. 
 + 
 + 
 + 
 +==== Overview Acquisition ==== 
 + 
 +As of March 2019 there is a feature to acquire an overview acquisition.  This is useful when the entire sample is many times larger than the instantaneous field of view.  The overview image is a 2D image representing a thin slice of the sample which can be collected relatively quickly.  After acquisition, a rectangle is placed on the overview image representing the current stage position, and this rectangle moves with the stage as long as positions are being updated.  It is not intended for use with a Z grid but only XY grid. 
 + 
 +Some settings for the overview acquisition reside on the "Data Analysis" tab.  These include the downsample factor for XY and for slice spacing.  The fractional thickness specifies how much of the entire image will be max projected to form the overview image.  You specify a channel and a side to run the overview acquisition with. 
 + 
 +Running the overview acquisition with the thus-labeled button uses the current settings of the XYZ grid GUI for X and Y (if they are enabled) and will overwrite any existing position list. 
 + 
 + 
 +==== Planar Correction ==== 
 + 
 +This feature allows compensation for small deviations from completely horizontal sample mounting, which results in the sample leaving the FOV when X and Y are moved without moving Z.  When planar correction is enabled the Z position will very slightly move uniformly as the X position is scanned.  The slope is specified in Z movement proportional to X and Y positions plus an offset. 
 + 
 +The plugin can compute a the slopes and Z offset if you mark multiple XYZ positions where the sample is centered vertically and use the button "Compute correction from position list" Alternatively the user can simply enter values themselves. 
 + 
 +Use requires BNC cable between PLogic #3 and TTL input of the Z axis card for proper triggering. 
 + 
 + 
 +==== XYZ Stage Limits ==== 
 + 
 +The purpose is to allow the user to define "limit planes" that need not be exactly along the X Y or Z axes.  This works in live mode based on the periodically-updated positions.  No provision is made to enforce these limits during acquisition. 
 + 
 +Specify the plane as satisfying a series of equations of form: A1*x + B1*y + C1*z < D1.  As a simple example, if you wanted to keep x between +1000 and -2000 then you would add the constraints 
 + 
 +A1=1, B1=C1=0, D1=1000 
 +A2=-1, B1=C1=0, D1=2000 
 + 
 + 
 + 
 + 
  
 ==== Channels ==== ==== Channels ====
  
 The channels feature is patterned after that of Micro-Manager’s [[https://micro-manager.org/wiki/Micro-Manager_User%27s_Guide#Multi-dimensional_acquisition|Multi-Dimensional Acquisition]]). It is most commonly used to take volumes with different illumination wavelengths (e.g. 488 nm and 561 nm for samples labeled with GFP and mCherry). Before using this feature, you must create and configure a group of presets containing the settings for that channel. The channels feature is patterned after that of Micro-Manager’s [[https://micro-manager.org/wiki/Micro-Manager_User%27s_Guide#Multi-dimensional_acquisition|Multi-Dimensional Acquisition]]).

Before using this feature, you must create and configure a group of presets containing the settings for that channel.
-Simple per-volume channel switching is implemented unless a Programmable Logic Card (PLC) is present in the controller; this mode is generic and can be used with any Micro-Manager group. PLC-based channel switching is hardware-based, requiring extra setup time but then no delay during acquisition. Using the PLC, channel switching is possible on both a per-volume and per-slice basis. In this case the channel group must contain the property Output Channel” which is used to select the correct laser to triggerother properties in the channel group, if any, are ignored.+ 
 +Simple per-volume channel switching is generic and can be used with any Micro-Manager configuration group. Control of the acquisitions reverts to Micro-Manager between volumes so that Micro-Manager can e.g. move filter wheels to the specified positions, and then the ASI controller is re-triggered by Micro-Manager to collect the next volume.  The plugin requires a certain amount of time between finishing one volume and beginning the next so that the extra communication and control change can happen. 
 + 
 +Alternatively there are two hardware-based channel switching modes -- "Every volume (PLogic)" and "Every slice (PLogic)" -- which which leverage the PLC so that TTL triggering which happens within each volume continues across all volumes and control of the acquisition never returns to the host PC.  These hardware-based channel switching modes require a bit of extra setup time but no delay during acquisition.  The main limitation of the hardware-based channel modes is that they will only change the channel via the PLC property "Output Channelwhich is used to select the correct laser to trigger (other properties in the channel group, if any, are ignored).  Mode "Every slice (PLogic)" interleaves the channels within the volume whereas "Every volume (PLogic)" changes channels between volumes.

 Distinguishing two nearby point sources of light is a classic problem in optics. If a camera’s pixels are so large that both points are read by the same pixel, you won't be able to tell them apart, regardless of how good the optics. The camera resolution must be at least twice the optical resolution to avoid being the limiting factor; essentially, a dark pixel must be between the two bright pixels. This is a manifestation of the Nyquist sampling theorem, which describes a fundamental mathematical relationship between continuous (or analog) and discrete (or digital) signals. Distinguishing two nearby point sources of light is a classic problem in optics.

-The standard formula for the optical lateral resolution is the Rayleigh criterion, a distance given by the formula: 0.61*lambda/NA (where lambda is the wavelength of light). For a 40X 0.8NA objective with 500 nm light, the lateral resolution is ~381 nm. That objective with a camera sensor that has a 6.5 um pixel pitch, is spatially sampling at (6.5 um/40X) ~162.5 nm pixel size, so we meet the Nyquist criteria (because 381 nm/162.5 nm = 2.34), but we wouldn't if we were using 400 nm light. + 
-Normally, for axial resolution limited by optics, the Z-axis step must be smaller than twice (per Nyquist) the optical axial resolution. Optical axial resolution, or depth of field, is usually taken to be lambda/(NA^2); for the 40X 0.8NA objective at 500 nm, it is ~781 nm.

 For diSPIM, we have two views that can be merged computationally. The axial perspective from each objective is a lateral perspective (with higher resolution) from the other, so we can undersample in Z to a certain extent, which is advantageous from a speed perspective. However, giving up too much axial resolution the registration of the two views will suffer; in an extreme case your Z-step could be large enough to completely skip over a point source. For this reason, we recommend the Z-step be at least as small as the objective's depth of field. (With Fiji MVR and bead datasets, it's easy to register datasets with 0.5 um Z-step spacing but not with 1 um Z-step spacing.) For diSPIM, we have two views that can be merged computationally.

 +===== Synthetic Stage =====
 +
 +Sometimes it is handy to create a synthetic stage to move the sample relative to the optic axis, e.g. to move deeper into the sample along the imaging axis by moving the SPIM head and the X axis of the XY stage together.  In the hardware config wizard add an instance of the Utilities > Multi Stage device which creates a synthetic 1D stage out of 2 real 1D stages.  Specify which stages to use and the scale factors in the properties in the System-Startup group in your hardware config.  The scale factors should be +/- 1 for 45 degrees, +/- 1 and +/- 2 for oSPIM at 60 degrees, and so forth.
 +
 +In order to use one axis of an XY stage as a 1D stage for the Multi Stage device you can use the Utilities > Single Axis Stage device.  Set its properties in the System-Startup group as well.
 +
 +Once set up, it is likely best to use the new Multi Stage device via the Stage Control plugin rather than assigning it as a stage in the Micro-Manager plugin.
 +
 +===== Acquisition Playlist =====
 +
 +The acquisition playlist allows you to run multiple acquisitions in sequence.
 +
 +You can drag and drop to reorder the acquisitions in the playlist. When you select an acquisition or position list, the previous item is automatically saved. You can also use the save button in the top right corner to save changes manually.
 +
 +To change what position list an acquisition is using, select the acquisition in the table, and click on the name of the position list in the "Position Lists" section. If an acquisition does not use a position list, select "None".
 +
 +When the "Run Acquisition Playlist" button is clicked, the plugin will automatically set acquisition failures to quiet and send any errors it encounters to the "Acquisition Status" text area. The plugin will automatically select "Save while acquiring" on the acquisition panel and close acquisition display windows after each acquisition.
 +
 +You can raise the diSPIM head between acquisitions by enabling the option in the settings tab, this will use the "Load Sample" position on the navigation tab as the position to raise the diSPIM head to.
 +
 +A note on channels: The plugin only saves channels with unique preset names, if two channels have the same preset only one of them will be saved. Also, only the used channels are saved, meaning the "Use?" checkbox must be checked.
