Dear Sirs, is it possible to include "FilterMCBunches" method at the beginning of readout simulation procedure? I have noticed that this step creates huge files, with information density tending to zero. For example I took your StdHep file of - 145 Mb, this produced slic output of - 888 Mb, (already here one could save some bytes) filtering gave - 26 Gb!!!! readout simulation - 1.3 Mb, reconstruction - 2.6 Mb. Is it really necessary to write so much on disk? Do we have too much disk space? Best Regards, Mikhail. ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the HPS-SOFTWARE list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=HPS-SOFTWARE&A=1
