I merged 3 data bases resulting in a new one with different size from the one shown in a demonstration..however my input is the same as the demonstration . https://usegalaxy.org/u/abdelazeem/h/final This is my analysis ... The demonstration analysis is here in this link below https://usegalaxy.org/u/coursera/p/genomic-data-science-with-galaxyidentify-polymorphic-sites
The version of the SAMtools used is different for these steps (the default version has upgraded since the tutorial was created). Nothing else looks incorrect. I am running a few more tests to make sure there isn't something else going on and will write back if so.
To replicate the history exactly, including the tool versions, use the workflow.
Thanks, Jen, Galaxy
