Hi Max,

The error indicates that the length/duration of a first-level covariate file from at least one subject/session differs from the length/duration of the functional data for the same subject/session. This mismatch can be caused by a number of different issues, depending on exactly how you input and/or preprocessed the data. 

Hope this helps

Alfonso

Dear Alfonso, I also confronted this problem recently when I used CONN 18.a.  I have used the completely same settings in CONN 16 before, and it works well. The error information appears at the step 5/7: Importing ROI data. Strangely, this error is persistent even I did not import any ROI files. Could you help me to figure out the reasons. The error information is as follows: ERROR DESCRIPTION: Error using horzcat Dimensions of matrices being concatenated are not consistent.
