Hello, I'm quite new here.

I'm just following a tutorial based on the folding Trp Cage Amber tutorial.

When I try to do the minimization with the following code:

pmemd -O -i 1min.in -o 1min.out -p TC5b.prmtop -c TC5b.inpcrd -r 1min.ncrst -inf 1min.mdinfo

it returns me:

"Error: Error from the parser: syntax error.

Check for typos, misspellings, etc. Try help on the command name and desc on the command arguments"

It seems that there is a syntax error but I can't find out which is it.

Could someone help me? Thank you very much
