Hi all,
We'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:
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
Note that we specified -notask. This ran fine.
We then tried to run selxavg3-sess using this command:
selxavg3-sess -s . -a lhippo_fcfsfast-analysis/ -no-preproc -no-con-ok
and get this error:
ERROR: not enough columns /r2/users/fspace2/RestData/091208RU_MR/bold/020/wm.dat
ans =
116 1
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!!!
