Program to process .txt chain files produced by CosmoMC (cosmologist.info/cosmomc) Calculates statistics, thins, produces 1D and 2D marginalized plots and scatter plots and writes out useful information. Option to adjust priors and map parameters - write code below Output files are (depending on options) file_root.margestats - the mean, limits and stddev from the 1D marginalized distributions file_root.likestats - the best fit, and limits from the N-D confidence region file_root.m - MatLab .m file to produce 1D marginalized plots file_root_2D.m - MatLab .m file to produce 2D marginalized plots file_root_3D.m - MatLab .m file to produce 2D sample plots colored by a third parameter file_root_tri.m - MatLab .m file to produce triangle plots (1D on diagonal, 2D off-diagonal) file_root_thin.txt - thinned merged versions of input files file_root.covmat - covariance matrix for parameters file_root.corr - covariance matrix for parameters normalized to have unit variance file_root.PCA - human-readable file giving details of PCA, constrained parameters, etc file_root.converge - Various statistics to help assess chain convergence/sampling error You can easily edit the .m files produced to produce custom layouts of plots, etc. Data for plots are exported to the plot_data_dir folder, other files to out_dir March 03: fixed bug computing the limits in the .margestats file May 03: Added support for triangle plots Dec 03: Support for non-chain samples, auto-correlation convergence, auto_label, split tests to quanify sampling error on upper and lower quantiles Jan 05: MatLab 7 options, various minor changes Jul 05: Added limits info to .margestats output Apr 06: Fixed some version confusions Aug 06: speeded 2D plotting Oct 06: Added plot_data_dir and out_dir Nov 07: uses Matrix_utils, fixed .ps file output filenames, added markerxxx for vertical lines in 1D matlabl plots May 08: Option to process WMAP5-formatted chains (thanks to Mike Nolta) Added font_scale to scale default font sizes, num_contours input parameter (allows more than 2) Sept 09: use of .paramnames and parameter_names file for names and labels; referencing by name as alternative to number allowed map_params with 1-column input format plotparams parameter ordering is preserved (e.g. to change order of 1D plots) Oct 09: fixed bug in credible intervals with prior cutoffs (Jan Hammann) May 10: added finish_run_command to run system command when getdist finished (e.g. "matlab < %ROOTNAME%.m") added line_labels to write out roots of lines being plotted (matlab) added no_triangle_axis_labels Jan 11: fix to confidence interval calcaultion for obscure cases with very empty tails (thanks Andrew Fowlie) Jan 12: increased precision of output files Oct 12: plot_output for pdf,eps,ps output support; subplot_size_inch fix for more than 100 parameters Nov-Dec 12: removed sm support; use specific parameter in triangle plots; new R-1 definition, etc... .. Mar 13: numerous changes.. Apr 13: output .py files, converge_test_limit, etc. Oct 13: add other mean likelihoods to .likestats
