Structure prediction

Hi,

I am new to rosetta and just started working on some tutorials. I am currently trying to use AbPredict code to generate sample structures by trying to execute tutorial documents at https://zhuanlan.zhihu.com/p/82235565 and also at rosetta_bin_linux_2020.50.61505_bundle/main/demos/tutorials/AbPredict. However, I am having following questions. 

1. create_run.sh file at the rosetta_bin_linux_2020.50.61505_bundle has a syntax issue and the one with the link works perfectly.

hi,

I am trying to use RosettaAntibody in order to model a camiled heavy chain only antibody (pdb code: 1YC7_1).

when using the following command:

antibody.linuxgccrelease -exclude_homologs true -vhh_only -fasta 1YC7_1.fa | tee grafting.log

(I am using exclude_homologs in order to test its preformance, because this antibody structure is already solved and found in the database).

I get the following error:

I am trying to run RosettaAntibody3 to build an Fv hhomology model from an input sequence. I am following the documentation form here.

I am using the command: 

antibody.static.linuxgccrelease \
  -database $ROSETTA_DATABASE \
  -fasta /mnt/data/input/myinput.fasta \
  -nstruct 1 \
  -out:path:all /mnt/data/output/output-graft/ \
  -detect_disulf false

 which fails fairly quickly with the error:

Dear Rosetta experts,

I have been using rosetta mainly for refinement and iterative local rebuilding into cryo-em densities at reolustions of ~3-3.5 Angstrom. I am wondering how (or if it is possible) to combine and complete a set of backbone fragments predicted by external software into a single backbone trace using rosetta. To make matters somewhat more complicated I would need to do this without any sequence information using only polyA fragments.
