[Marsbar-users] extracting FIR timecourses

[Ana R. <ana...@du...>]

Hi all,

I am trying to extract FIR timecourses in a study that uses a sparse-imaging
design with a TR=10.2s. The first 8.6s of the TR are a silent period (during
which a spoken sentence was presented) and the last 1.6s correspond to the scan
acquisition. Is it possible to extract timecourses in a sparse-imaging
design with such TR?

When I try the script in
http://marsbar.sourceforge.net/faq.html#extract_fir

I get the following error message:

??? Error using ==> event_fitted_fir
Too many input arguments.

Error in ==> /work/imaging/Functional/KTB/ffx/marsbar_batch.m
On line 95 ==>   fir_tc(:, e_s) = event_fitted_fir(E, e_specs(:,e_s), bin_size,
...


Any suggestions of what may be causing the error and how to fix it would be
great.

Thanks in advance!
Ana
