Installing rna_denovo

Hi,

I tried using the Rosetta RNA tertiary structure modeling pipeline as described in your article “Modeling complex RNA tertiary folds with Rosetta.”

My build is correct.

But every time I try to run

helix_preassemble_setup.py -secstruct sec.txt -fasta fasta.fasta

I am getting error as

subprocess.check_call([str(elem) for elem in cmdline.split()])

  File “/usr/lib/python2.7/subprocess.py”, line 185, in check_call

    retcode = call(*popenargs, **kwargs)

  File “/usr/lib/python2.7/subprocess.py”, line 172, in call

    return Popen(*popenargs, **kwargs).wait()

  File “/usr/lib/python2.7/subprocess.py”, line 394, in __init__

    errread, errwrite)

  File “/usr/lib/python2.7/subprocess.py”, line 1047, in _execute_child

    raise child_exception

OSError: [Errno 2] No such file or directory

going back to the code, in line 75,

“rna_denovo -score:weights stepwise/rna/rna_res_level_energy4.wts -minimize_rna true -use_legacy_job_distributor true -restore_talaris_behavior true “

this rna_denovo is called.

But, in rosetta bin there is no .exe called rna_denovo, instead I found,

rna_denovo.default.linuxgccrelease

rna_denovo.linuxgccrelease

rna_denovo.static.linuxgccrelease

not sure, why is name mismatch and how to call rna_denovo.

So my pipeline is not working.

Can you help me resolving this issue?

Thanks,
