hello everyone Does anybody knows why refmac5 will not process any model that contains thymine in its structure? This problem only happens on my PC which supports a 2.1.0 version of ccp4i. The error in the log file says its due to bad value during floating point read. However, this problem never happens on a linux based computer in our lab which supports an older version of ccp4i. Version 2.0.4 specifically. This problem extends over to coot as well. It would not process any mtz files if the model used contains any thymine. Again, this problem only happens on my PC but not on the Linux based computer. Coot's log file says the reason it failed is because it encountered a new ligand and which caused the refmac to shut down. Any feed back on this problem would be much appreciated. Thanks.
