??? Undefined function or method 'file2mat' for input arguments of type 'struct'.

I'm trying to run some functional connectivity analyises on the ABIDE data by using DPARSFA and, just after applying the Reorientation Matrices (downloaded from http://www.restfmri.net/forum/DownloadedReorientMats), I get the following error (pasted below)
I saw that someone posted something similar last september but could find any response. Sorry if I missed it...

Please, can someone help me with that?

Thanks in advance and happy friday!
