Hello, I just watched your YouTube video "Structure-Based Virtual Screening on the Cheap" and wanted to try the sdsorter program you mentioned, however on my linux box sdsorter.static gives the same error as the above message from Laura MC above, ie. sdsorter.static: loadlocale.c:129: _nl_intern_locale_data: Assertion cnt < (sizeof (_nl_value_type_LC_TIME) / sizeof (_nl_value_type_LC_TIME[0])) failed. Aborted (core dumped) Can you take a look? Thanks, Greg
