-As of April 2015 allows for direct importing of Micro-Manager datasets collected by the ASIdiSPIM plugin (rendering the plugin's export function obsolete for MVR analysis).+As of April 2015 the MVR plugin allows for direct importing of Micro-Manager datasets.  Previously the Micro-Manager plugin's export function was used (it is still required for [[MIPAV GenerateFusion]]).

 +==== Fiji MVR scripts ====

 +This script was used during the 2018 EMBO Practical Course for Light sheet microscopy in Dresden to roughly align two views collected on the ct-dSPIM:

 + *  Simple script to deskew, flip and move a DiSPIM dataset 
 + *   
 + *  Olivier BURRI, Jon Daniels 
 + *  EMBO Lightsheet Course 2018 
 + *   
 + *  INPUT: XML file which contains two angles named 0 and 90 
 + *   
 + *  This will apply the transformations to the XML file and reopen the multiview applications
