[Chimera-users] rna model

[Elaine Meng]

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.

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
