Bob,

Thanks for your response to my question about using 1D files with waver, but I am now having probelms with your suggested solution.

I am using the following command to generate a reference function from a 1D file that contains mulriple columns of stimulation times:

waver -GAM -peak 1.0 -dt 1.0 -tstim `1dcat ../PVT_Times/'01_pvt_n.1D[0]'` > ../01_n/PVT/01_pvt_n_Hit_RF.1D

However, only the first entry in the specified column is being used by waver. Oddly, when I use a 1D file with only 1 column and 'cat' instead of '1dcat' it works fine. Am I doing something wrong with my 1dcat?

Thanks.

Sean
