Hi AFNI Experts,

I'm running a 3dMVM with 304 participants and several between subjects variables. I get the following error during the reading of input files:

** Error:
Problem with input files! Two possibilities: 1) There is a specification error
with either file path or file name. Use shell command 'ls' on the last column in the
data table to find out the problem. 2) At least one of the input files has different
dimensions. Run "3dinfo -header_line -prefix -same_grid -n4 *.HEAD" in the directory
where the files are stored, and pinpoint out which file(s) is the trouble maker.
Replace *.HEAD with *.nii or something similar for other file formats.

I have double checked the file paths and file names and they are correct. I have also double-checked the input file dimensions and they are all the same. I'm not sure what else could be causing this error in reading in files. Any help would be appreciated!

Best,

Juliann Purcell
