Hi-

We have blocks that are not the same length for every subject.

So I was wondering if it is possible to make block-length in the 3dDeconvolve function variable, as in:

3dDeconvolve -input ${sub}-rl-norm_at+tlrc \
-censor ${sub}-motion_censor.1D \
-jobs 8 \
-polort A \
-mask ${sub}-mask_at+tlrc \
-concat /data/brutus_data1/home/jwaltz/ana/pessig/scripts/RLCat.1D \
-num_stimts 12 \
-local_times \
-basis_normall 1 \
-stim_times 1 /data/brutus_data1/home/jwaltz/ana/pessig/${sub}/GAINvMISS_All_PosPE.txt 'BLOCK(X,1)' \

Where the specification of the block-type regressor can actually 'd' (duration) as a variable.

In this case, does it just make more sense to specify the regressor as a time series?

Thanks,

Jim Waltz
