[VoxBo] idl, vbview, and single-user VoxBo

[Katharina Spalek]

Dear VoxBo-users,

I'm trying to reanalyze some data for a paper, but unfortunately, I'm no 
longer at Penn, hence, data access is more difficult. I've been trying 
for about a month to get a VPN account to access my data that still live 
at the CfN-cluster, but somehow it still doesn't work.

Desperately, I'm now trying to do the analyses with single-user VoxBo, 
using my copy of the data. Some things are trickier than at the CfN, 
because I have neither an IDL nor a matlab-license. However, I believe 
that Dan tried to replace the functions of the IDL voxel surfer with 
vbview, and hence, I was wondering if I can do the things I have to do 
without IDL.

Here's what I need to do and how I would have done it with the voxel 
surfer: I want to save functional regions of interest based on the 
activation of all experimental conditions compared to all control 
conditions. In IDL, I would have: Loaded an nDisplay.cub. Overlayed it 
with a foo.prm file (from an rfx-analysis). Thresholded it with the t 
for p < .05, as calculated in a permutation analysis. Selected all 
contiguous voxels within a region and saved them as a mask. Done the 
same for the next region of contiguous voxels. (And afterwards, run the 
vbdumpstats command to look at each participant's specific values within 
these regions of interest).

Is it possible by now to do this in vbview? My first hurdle is trying to 
overlay the nDisplay.cub with the foo.prm, vbview complains that it is 
not possible to load the statistical overlay.
If this has been discussed previously, just lead me to the correct 
thread and I'll find the necessary information in the archives.

Thanks in advance,
Katharina
