Hi Ece,

I did make a small change to allow for this, however I think this is not a great place to
do it. In your case, I think you should catenate the 1D files and use -concat.

However (once the update is distributed), your command should work, with a couple of
changes: 1. since you are abusing the 3D functions handling 1D files, your datasets
need to be transposed on input, and 2. -force_TR is needed, since 3dDeconvolve
will not be able to tell the TR of your datasets.

The better way for us to go would be to allow -input1D to handle multiple inputs, but
that would be too much like work.

In any case, it seems most straightforward to apply a single input and use -concat.
