Hello:

I am using 3dDetrend in my PPI analysis and I am running into an issue with the 1D files that it creates. here is the command I am using:

3dDetrend -polort 1 -prefix ${ID}_${STATE}_R1_L_INSULA_SEED_R ${ID}_${STATE}_R1_L_INSULA_SEED.1D\'

What I want is the values in the time series after removing the trend but what it gives me is the values along with the number of voxels in the seed region. Example:

0.01234 (709 voxels)

The non-numeric characters are creating problems in further processing commands. Is there a way to completely eliminate the "(709 voxels) from the output 1D file? I tried -ok_1D_text but it turned all of the text into zeros and I don't think I want that.

Any help would be greatly appreciated.

Thanks!
