I am trying to use phenix.hyss to find 50 Se sites from my MAD data. Phenix.hyss has been running for more than 24 hrs now and is still going. I have 4 GB memories on my workstation. Phenix.hyss used more 95% of it and makes the machine basically unusable now. Is it normal for phenix.hyss to use so much memories? I am using Phenix 1.24.1b.
