Hi,
I'm attempting to use fsl_regfilt to remove some confounds from a
timeseries. I have a 4d image and a design matrix text file with 18
columns and the same number of rows as there are frames in my
timeseries.
I am invoking fsl_regfilt like so:
$ fsl_regfilt --in=bold_mcf_st --out=bold_mcf_st_regfilt
--design=confound_matrix.dat
--filter='1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18' --mask=mask
However, when I run this, I get the following error:
ERROR: need to specify 4D input to use filtering
However,
$ fslinfo bold_mcf_st
filename bold_mcf_st.nii.gz
data_type FLOAT32
dim1 128
dim2 128
dim3 67
dim4 60
...
What gives? That looks 4D to me. I'm sure it's something simple I'm
missing, but the documentation for this program is rather sparse...
Thanks,
Michael
