Utility to chop physio measures (voltages) from Siemens Physiologic Monitoring Unit (PMU) and generate respiration volume per time (RVT) regressors for a single MR protocol with AFNI's RetroTS.py
This is for you if you want 1D inputs for 3dretroicor or afni_proc.py (ricor block) and have physio recordings (*.resp and *.puls) files the look like this:
1 2 40 280 ... [measure's full timeseries on a single line]
ECG Freq Per: 0 0
PULS Freq Per: 74 807
RESP Freq Per: 20 2860
....
6003
siemphysdat respfile pulsefile MRdir
# or
siemphysdat respfile pulsefile -j BIDS_protcol_info.jsonlook for new *dat (chopped physio) and *slibase.1D (RVT regressors, ready for -ricor in afni_proc.py) files
run ./prepareForDemo.bash and follow instructions.
works on files included in data/ and save output to data/phys
see siemphysdat -h, perldoc siemphysdat, or ./prepareForDemo.bash

RetroTS.py and dicom_hinfo from AFNI are likely to be used and should be in your PATH.
See which dicom_hinfo to check.
N.B. We now default to RetroTS.py, which has a bug fix. If you really want to use the matlab code,
you should have afni's matlab scripts and they should be your MATLABPATH (e.g. export MATLABPATH="$HOME/afni_matlab:$MATLABPATH")
RetroTS.m works with octave but all afni .m functions must have | and & replaced with || and &&
