Dear Alphonso,

I am processing a 14 subjet dataset to perform dynamic ICA analyses. Preprocessing runs smoothly. However, every time I click 'Done' to move on to the Denoising step, I encounter this error:

ERROR DESCRIPTION:

Error using conn_process (line 760)

The trouble seems to be with a CSF segmentation file. Moreover, this error initially kept occurring on subject 7 (ironically while the program displayed processing subject 6). In that instance, I tried using an older version of dcm2nii to convert the structural scans. While that solved the problem for subject 7, I now have this error message happening for subject 14 (again occurring while the program seems to be processing subject 13). 

Is this an image dimension issue? Any advice on how to remedy this issue?

Many thanks,
Jeremy
