Hi FSL experts,
I am running a FEAT higher level analysis combing four runs for multiple contrasts. I have 5 contrasts, and for one of these contrasts I get the following error for all of my subjects:
WARNING: The passed in varcope file, tmpvarcope0072, contains voxels inside the mask with zero (or negative) values. These voxels will be excluded from the analysis.
nevs=33
ntpts=132
ngs=1
nvoxels=0
Running:
nmaskvoxels=0
From reading previous emails, I know that this is nothing to worry about - but as a result of this error, I am not getting any resultant activation and all of the zstat plots are empty. When I look at the individual runs, there is plenty of activation that should be apparent when these runs are combined.
I looked at my varcope file and the min voxel is 0 but within the file it self there are plenty of positive values. Any idea how to fix this?
Thanks,
Danielle
