Hi,
I tried to understand some details of the featquery command and looked
through logs and sources.
I stumbled in the log upon this line:
/usr/local/fsl/bin/fslmaths stats/pe1
/path/to/the.gfeat/cope1.feat/query_2_cluster_2/tmp
I was a bit confused by this fslmaths syntax and tested what it does. It
simply copies the file. I wondered why it is used instead of imcp.
➜ stats$ time imcp zstat1 test
imcp zstat1 test 0.04s user 0.07s system 195% cpu 0.060 total
➜ stats$ time fslmaths zstat1.nii.gz test.nii.gz
fslmaths zstat1.nii.gz test.nii.gz 1.44s user 0.12s system 95% cpu
1.628 total
Why it is used here? The imcp seems to be much, much faster.
Thanks,
Andrej
