Hi everyone,

I'm trying to use CONN to analyze both rfMRI and tfMRI data from the Human Connectome Project. I have some questions regarding input.

1. Since HCP provides pre-processed fMRI data that is already co-registered to the MNI space, can I simply supply a standard MNI structural image into the Structural tab, such as a MNI152_T1_2mm.nii.gz file from the FSL data directory in lieu of providing each subjects co-registered structural data? (aren't they the same now?) Also, can CONN only read files from WRITABLE directories? (if I'm reading data from a cluster, I would have to copy all the data that I need into a local directory before performing the analysis?)

2. When I tried to load a HCP rfMRI data into the Functional tab, I was returned with the following error. Anyone know what this implies?
ERROR DESCRIPTION:

Thank you in advance!
