Hello,

I am trying to run 3dfim+ to calculate a correlation map for a region of interest. I deobliqued the data (the functional and the ROI mask which was converted to the same functional space) with 3drefit -deoblique (because I was getting an error message about data being oblique). However the deobliqued functional image now doesn't have the time dimension and the 1D file I'm getting when extracting timeseries from a ROI mask applied to this functional only has one number in it (884.727 [264 voxels]). Isn't it supposed to be a column of averaged voxel intensities in this ROI for each time point? Where did all the timeseries go?

When I try to run 3dfim+ I receive the following error:


<p> Standard output:
Matrix error: Incompatible dimensions for vector multiplication: 0x0 X 1
** Memory usage: chunks=84 bytes=621942
Standard error:
++ 3dfim+: AFNI version=AFNI_2011_05_26_1457 (Jun 22 2011) [64-bit]
++ Authored by: B. Douglas Ward
3dfim+ main
Return code: 1
Interface Fim failed to run. </p>

The command I try to run is
<p> 3dfim+ -input /path/mcorr_001_brain_3drefit.nii.gz -ideal_file /path/mcorr_001_brain_3drefit_maskave.1D -out Correlation -bucket corr_map.nii.gz </p>


Does anyone have any idea what might cause this problem?

Thanks a lot!
