Will BaseRecalibrator overwrite an existing .grp file? Where are the tmp files stored?
I've been running BaseRecalibrator for a while, and I've just realized that I have an empty file with the same name I've given to BaseRecalibrator as output (it may have been created from a previous aborted run). Will the tool write to this file when it is finished (ETA ~19 hours), or will it exit with an error? Also, are there any intermediate files created in generating the recalibration table, and if so, where should I look for them (output directory, log directory, directory from which I called GATK, ...)?
