Re: [ccp4bb] secondary structure prediction
Thanks for many advices. I was not clear in the previous email. I know the close homologous protein (20% identity, total 500aa), but the fragment hits (30~40aa, identity 40~50%) are from other proteins in PDB. I am trying to see whether the fragments from non-homologous proteins may help the secondary structure prediction.

Re: [ccp4bb] How to find the Rfree and R in the highest resolution bin in Refmac 5?
You can find these numbers in the header of the output model coordinate file. BR From: CCP4 bulletin board [mailto:CCP4BB@JISCMAIL.AC.UK] On Behalf Of Xiao Lei Sent: Wednesday, December 6, 2017 2:40 PM To: CCP4BB@JISCMAIL.AC.UK Subject: [ccp4bb] How to find the Rfree and R in the highest resolution bin in Refmac 5? Dear All, I am asking how to find the Rfree and R in the highest resolution bin in Refmac 5 output? I used Refmac5 in refinement of protein structure at 3A resolution. Output of Refmac5 gives Rfee and R as: InitialFinal R factor0.2900 0.2052 R free0.3015 0.2639 I'd also like to see the Rfree and R in the highest resolution bin. I checked log file in Refmac5 and found M(4SSQ/LL) resolution range table with columns of Rf_free and WR_free, I searched in internet and still could not understand the Rf_free and WR_free label meaning. I'd like to find something like Rfree XXX (XXX); R XXX (XXX) (the highest resolution bin value in the parenthesis). thanks ahead.

Re: [ccp4bb] secondary structure prediction
I would try your local bioinformatician (or a remote one if there isn't any one local). With the sequence in the mail, I could have given it a shot...
