Homer3 1.71.1 not saving group data to output file

I just recently updated my Homer3 and AtlasViewer softwares to try and solve some issues I was having with my Matlab contrast code. However, I have been having additional issues with the new versions and have discovered that Homer3 v1.71.1 is not saving group-level data (in the groupResults.mat) file. The mat file is created with the appropriate structure, but the dcAvg is blank. This does not happen at the subject level, just the group level. I ran the processing again and made sure to save it and had the same problem. When I try and load the files into AtlasViewer (2.18.1), the "Load precalculated profile" is grayed out. I think this is because the groupResults.mat is empty but I am not sure. Maybe that is a separate issue that I am having with AtlasViewer.

Any help to address/correct this would be appreciated.

I am using Matlab 2020a, on a pc.

Hi Lisa,

Can you email me at jdubb@bu.edu the Homer3.log log file from the Homer3 session that produced the issu. Homer3.log file is generated each time you run homer and is under the Homer3 root folder.

Also if it's possible share the dataset (or part of the dataset if it's large) on google drive or dropbox?

Hello! I am experiencing a similar issue (i.e., the group.procStream.output is empty). When using AtlasViewer, I get the error " There are no active channels and therefore no data to display" (I belive because "activeChLst_SDpairs" is empty). Any suggestions? Thank you very much

Hi Annalisa,

 

Was there a folder change or folder name change or you are launching AV under the same folder you did your homer analysis? And also please confirm you have group level results in Homer.

Dear Meryem,

Thank you for your feedback. I just tried with Homer-development and AtlasViewer-development, in case the issue was with the versions in my previous attempt. Unfortunately, I still get an empty group.procStream.output in my GroupResults following preprocessing. Any idea on what might be the issue? Thank you very much!

Annalisa
