Hello,
I am facing a problem in running "auto_tracing" in arp/wrap. At first I have tried using command line mode however I missed R-free value. I have added the "freelabin " FREE=FREE "" and have got an error "Refmac_5.5.0102: Error in label assignments in LABIN" In another way, I used ccp4i, here also the error was appeared as "Cannot extract ARP/wARP asymmetric unit limit." I guess the root of both errors are same. Have somebody faced same problems before? Could you tell me that how this type of problem can be solved? Regards, Rojan
