From 2015, CSPM uses a new file format for physiology. The old one was "hd2000", which ran separately, but which was very clunky.
Raw data
In the study data folder, the "raw" data is from whatever recording we had: Biopac, IFF-PHYS, instrunet,or WHH. The "phys" folder contains the data in a universal format. (The MRI equivalent is DICOM, PAR/REC, Analyze for the raw, and nifti for the converted.)
phys folder
Each channel is saved as a MATLAB timeseries object, with asynchronous (that is, not necessarily uniformly sampled) time values.
