[VoxBo] vbdumpstats and timeseries question

[Ranjani Prabhakaran]

Hi,

I'm trying to use vbdumpstats to get ROI beta values.  I saved a  
functional mask for a subject and then used vbdumpstats to get the  
beta value for the voxels in that mask.  According to vbdumpstats,  
there are 48 voxels in that mask.  But when I loaded my .prm file  
using idl, applied the mask, and checked the number of voxels - there  
are supposed to be 101 voxels in the mask.

Also, when I use the idl "Find All" tool to find out how many voxels  
are in the mask, I've been getting the following message:

(21) No time-series available for requested region
[called from: READTIMESERIES </usr/local/VoxBo/pros/VoxBo_10.pro(1712)>]

The glm for the subject ran without any problems and I can load  
the .prm file in idl, so I'm not sure what the source of this problem  
is.

The subject's glm is located here: /xjet/prabhakr/michigan_celeb_cfn/ 
s16_cfn/models/s16_collapsed_gs

And the subject's masks are located here: /xjet/prabhakr/ 
michigan_celeb_cfn/s16_cfn/Anatomy/LIFG_Masks

Any ideas about why I'm getting this message and why there's a  
discrepancy in the number of voxels reported in the mask?

Thanks in advance for your help!
