When I run it, a number of files with different extensions are created. What are they all?
For a simple run there will be three files: one “.ppp” file, one “.dat” and one “.txt”. The .ppp file is the Psics Pre-Processed form of the model. This is a complete description of the model as it is to be run, with tabulated transitions rates for the ion channels and details of the compartements making up the discretized form. The .ppp file is the only input to the core calculation, so if PSICS is running on a grid, it is this file that gets moved around to the separate nodes. The .dat file contains the raw results as binary data in the order in which they arrive. The core calculation simply writes to the end of the file as it goes along. The .txt file is created for plotting convenience. It contains the same data as the .dat file but formatted as text. Also, if the .ppp file model specifies multiple runs with the same parameters, these pile up one after another in the .dat file. In the .txt file they are rearranged into columns with just one set of time points in the first column. I
