Hi FSL experts,
I am trying to perform cluster correction on F-tests (2x3 interaction) with very large (within sub and between sub) designs that were run in flameo.
when using the command:
ftoz -zout fzstat fstat1 134 24
I am getting the following error when converting some, but not all, of the F stat files to Z stat files:
"ndtri domain error"
Then when running the cluster correction ...
fslmaths fstat4.nii.gz -mas mask.nii.gz cluster_correction/fstat4_mask.nii.gz
cluster -i fstat4_mask.nii.gz -t 3.1 -o fstat4_clusters_3.1 -d 0.043 --volume=234781 -p .05 --othresh=fstat4_thresh_3.1.nii.gz > cluster_info_wholebrain_3.1_fstat4.txt
It still generates the output file, but the resulting thresholded images don't look as they should; many small clusters outside the brain, ect.
Thanks,
|
