Hi all, <br><br>We&#39;ve been trying to use FsFast for functional 
connectivity analysis using the left hippocampus as the seed (isolated 
from aseg). We used the following command to make the analysis: <br>
<br>
mkanalysis-sess -fwhm 0 -fsd bold -mcextreg -polyfit 2 -TR 2.6 -analysis
 lhippo_fcfsfast-analysis -nuisreg wm.dat 3 -nuisreg vcsf.dat 3 -nuisreg
 global.waveform.dat 1 -taskreg l_hippo.dat 1 -notask -native<br>
<br>
Note that we specified -notask. This ran fine. <br>
<br>
We then tried to run selxavg3-sess using this command: <br>
<br>
selxavg3-sess -s . -a lhippo_fcfsfast-analysis/ -no-preproc -no-con-ok <br>
<br>
and get this error: <br>
<br>
ERROR: not enough columns /r2/users/fspace2/RestData/091208RU_MR/bold/020/wm.dat<br>
<br>
ans =<br>
<br>
   116     1<br>
<br>
This file has one column. And I assume that it is looking for multiple 
columns with which to do contrasts. However, this is resting-state data 
so there are no contrasts. Looking deeper into the selxavg3-sess code it
 seems that the -no-con-ok flag sets RequireContrast to 0. However, this
 does not get transferred to fast_selxavg3.m. DoContrasts = 1 in 
fast_selxavg.m. I think this is the problem. Any help would be greatly 
appreciated!!!<br>
