Hi all, I have SeMet data for which HySs locates 127 Selenium atoms with a CC of 0.31, which I think is decent. Then I run Phaser to generate the first maps, and it gives a score of 25 and LLG of 190 or so... The next step would be running Autobuild, however, the first models I realize it is building have R work and R free between 50 and 55%. So I guess it is just some random stuff there. If the result from HySS and Phaser looks more or less good, why does AutoBuild show these numbers?? Any idea of what I could do to improve so? Any ideas are welcome.
