Hi, 
Thankyou for the toolbox.
I have a set of 4D volumes that are preprocessed using SPM (sw_). During Preprocessing I have not used the first four volumes. But the preprocesed functional scans have those volumes included.The beginning of the 5th volume is considered as the time 't' = 0 for creating the onsets.txt.

Q1) Do I just set AnaDef.OnsetModifier = 4 in the anadef.m for discarding those volumes?
In the GIT Hub version of this code I found AnaDef.OnsetModifier is set as 5 for removing 4 volumes . Again that is when 3D volumes are being used.

Q2)Also Is there away to create multiple out_estimated.mat files if I have multiple files. Do i need to run for each one of them separately?

Thanks again
