Hi,
I am running the attached processing stream on my data, including PreprocessIntensity_NaN and PreprocessIntensity_Negative. However, I still receive negative and NaN HRF values in the .txt file. Is there something I am doing incorrectly, or does anyone have further suggestions?
Thanks!
Christina
My preprocessing stream didn't upload, so I'll put it below:
hmrR_PreprocessIntensity_NAN
hmrR_PreprocessIntensity_Negative
hmrR_Intensity2OD
hmrR_BandpassFilt: Bandpass_Filter_OpticalDensity hpf 0.000 lpf 3.000
hmrROD2Conc ppf 1.0 1.0
hmrR_GLM trange -2 30.0
glmSolveMethod 1
idxBasis 1
paramsBasis 1.0 1.0
rhoSD_ssThresh 0 (no short separation channels)
flagNuisanceRMethod 0.0
driftOrder 3
c_vector 0
Thanks for any input!
Christina
what txt file?
HRFs will have negative values.
HRFs can have NaNs, I think, if the channel was pruned... but your processing stream above is not doing any pruning it seems.
hmm... these two steps always work for us
hmrR_PreprocessIntensity_NAN hmrR_PreprocessIntensity_Negative
