Yes, if you spec to use motion correction regressors, then it will look for mcextreg_000.bfloat. This is created by motion correction. If that does not exist, then that process might have failed. To see, try

cd /Users/balajigoparaju/Desktop/subjectdata/LD-functional/bold/006
mcparams2extreg -mcfile fmc.mcdat -northog 6 -extreg mcextreg

Hi Doug and all, 

There is a problem when i try the individual statistics, 

I use the command
 selxavg3-sess -analysis LD-analysis -s LD-functional

and i am getting an error:

ERROR: cannot find volume matching /Users/balajigoparaju/Desktop/subjectdata/LD-functional/bold/006/mcextreg
ERROR: loading nonpar reg /Users/balajigoparaju/Desktop/subjectdata/LD-functional/bold/006/mcextreg
------------------------------------------
ERROR: fast_selxavg3() failed\n

The error seems to be something to do with a file needed to use motion correction regressors

so i was wondering if the problem was because the software is not creating the file, or if there was any other way i 
could make freesurfer create the file.

Thank you for any help!
