How to thinned the posterior samples?

[yanyuechuixue]

I use the script in run_files and get "gw150914_inference.hdf" file,
but it is not same with "gw150914_posteriors_thinned.hdf".

Could you introduce the method of how to thinned the posterior samples?

You need to run pycbc_inference_extract_samples on gw150914_inference.hdf file, but I'm not sure what thin interval settings @soumide1102 used. @soumide1102 can you comment?

It would be good to add the extract samples command to the repo, either as separate scripts, or as an addendum to the run scripts.

Hi @yanyuechuixue The "gw150914_inference_thinned.hdf" contains the thinned chains or independent samples extracted from the chains stored in the output file from the run "gw150914_inference.hdf". I've now added the commands for thinning the chains in scripts calledextract_independent_samples.sh in the events folders under run_files. You'll have to run the script for thinning with a version of PyCBC that is post v1.9.4 ( https://github.com/gwastro/pycbc/releases ).
