RosettaAntibody3 core.pose.util error
#1

I'm using rosetta_src_2020.08.61146_bundle. I'm trying to use the RosettaAntibody3 workflow as documented here, but am running into the following error when I run the following command:

module load rosetta/2020.08 blast/2.10.0+ gcc/9.1.0
antibody.default.linuxgccrelease -ignore_unrecognized_res true -fasta IL6antibody.fasta -out:path:all antibodied

Here is the IL6antibody.fasta file:

This is the error (with part of the preceding logging messages):

core.pose.util: [ ERROR ] Can't find residue type 'UNK' in type set of mode fa_standard

AN INTERNAL ERROR HAS OCCURED. PLEASE SEE THE CONTENTS OF ROSETTA_CRASH.log FOR DETAILS.

/var/spool/slurm/job15053608/slurm_script: line 5: 18463 Segmentation fault      (core dumped) antibody.linuxgccrelease -ignore_unrecognized_res true -fasta IL6antibody.fasta -out:path:all antibodied

This occurs whether I use the antibody.linuxgccrelease or the antibody.default.linuxgccrelease executable, and whether I have the flag -ignore_unrecognized_res or not.
