Dear all,

I cannot use AFNI to load/view or otherwise manipulate the rs-fMRI data recently released by the Human Connectome Project. I can view these same data in fslview and mricron.

A typical error message is,

** NANM: failed to alloc 3610516 bytes for brick 845

and more context is below.

I would be grateful for your help.

Best regards,
Mika

Thanks go to A Martin for much encouragement

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
The number of sub-bricks in one of your datasets exceeds
the current maximum of 1024. Some menus like Ulay/Olay/Thr
will not allow you to select sub-bricks beyond #1024.
To access all sub-bricks from such menus, increase the value of
environment variable 'AFNI_MAX_OPTMENU'. You can do so for this
AFNI session via the 'Edit Environment' plugin. For a more lasting
fix, add the line:
AFNI_MAX_OPTMENU = XXX
under the '***ENVIRONMENT' section of your .afnirc file with XXX
being a suitably large number.
For details, search for 'AFNI_MAX_OPTMENU' in AFNI's README.environment.
