RE: Preprocessing using Removal of initial scan in Conn18a resulted in dimensional mismatch among functional scans.
Hi
Sorry about that and thanks for reporting this issue. The problem seems to be in the GUI display, which is mis-reporting the dimensionality of the resulting functional series after removing a number of initial scans. I am attaching a patch to fix this issue (this patch is for conn18a, simply copy the attached file to the conn distribution folder overwriting the file with the same name there). After applying the patch please run the following commands with your conn project open, and then save your conn project to keep these changes (this step is just to avoid having to re-select your functional data and applying the removal of the first four scans again) :
f = conn_module('get','functionals');
conn_module('set','functionals',f);

Hi there,
I experienced the same issue. I have 240 functional volumes, and removing the initial 4 scans resulted in 56640 dimensions (appears to equal 236 x 240) for functional image of each subject.
Does anyone have suggestions on how to fix this in Conn18a, other than switching back to previous version? Thanks in advance!
