Hi Gang,
You're right -- it is very clear how to create the file AvsBcoding.1D. Where I'm a little confused is in the command below:
> 1deval -a Seed_Neur.1D -b AvsBcoding.1D -expr 'a*b' > Inter_neu.1D
Is the Seed_Neur.1D file the output from 3dTfitter? I'm assuming that it is. The error that I was receiving earlier was because I had to 1dtranspose the output of 3dTfitter to make it a single column of data the same size as my AvsBcoding.1D file.
Thanks,
Aaron
