Are your time series in a row or column? If I recall 3dfim+ likes the ideal file in a column. To convert from row to column is trivial, just add a ' at the end of your ideal file name on the 3dfim+ command line. Though you will more than likely need to add a \ before the ' in order to prevent the shell from interpreting it.

You command will look something like:
3dfim+ -input input+tlrc.HEAD -ideal_file EO_alpha_ps_conv_HRF_ts_normalized.txt\' -out Correlation -bucket correlation
