¥Step 1: creation of random
stimulus functions
_RSFgen :
Random Stimulus Function generator
_command file: c01.RSFgen
RSFgen
-nt 300 -num_stimts 3\ -nreps 1
50 -nreps 2 50 -nreps 3 50\ -seed
1234568 -prefix RSF.stim.001. _This creates 3 stimulus timing files:
RSF.stim.001.1.1D
RSF.stim.001.2.1D
RSF.stim.001.3.1D
¥Step 2: create ideal response
functions (linear regression case)
_waver: creates waveforms from stimulus timing files
"effectively doing convolution
_command file:
c02.waver
waver -GAM -dt 1.0 -input RSF.stim.001.1.1D_this will output (to the terminal window) the ideal
response function, by
convolving the Gamma variate function
with the stimulus timing function_output length allows for stimulus at last TR (= 300 + 13,
in this example)
_use '1dplot' to view these results, command: 1dplot wav.*.1D
