[Chimera-users] rna model

[Divita Mathur, Contractor Code 6910, FN]

Hi Elaine

Sorry, I should have been clearer. This was my command:
rna model /Users/dmathur/Documents/gapB-sfGFP-mRNA.fasta path #0
and
rna model /Users/dmathur/Documents/gapB-sfGFP-mRNA.fasta path #0 start 40 length 8

Both return the same error.

    Hi Divita,
    Is “rna model sequence  #0” actually the command you gave?  In the command usage, the word "sequence" (shown in italics) is supposed to be pathname of the file with the sequence in it (not literally the word "sequence"), and you are also required to either give the "path" option or the "pairs" option.  You cannot omit both.

    "rna model" help
    <https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/rna.html#model>

    how to read command usage in help pages
    <https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/rna.html#model>

    So if you had  the path markers as #0 then your command could be something like

    rna model /Users/divita/Documents/blahblah.fasta path #0

    (of course, change the pathname as appropriate for the detailed location and filename of your fasta file.)

    I hope this helps,
    Elaine
