```

## DESCRIPTION

**gmx wheel** plots a helical wheel representation of your sequence. The input sequence is in the *.dat* file where the first line contains the number of residues and each consecutive line contains a residue name.

## OPTIONS

Options to specify input files:

- **-f \[\<.dat\>\] (nnnice.dat)**

  Generic data file

Options to specify output files:

- **-o \[\<.eps\>\] (plot.eps)**

  Encapsulated PostScript (tm) file

Other options:

- **-r0 \<int\> (1)**

  The first residue number in the sequence

- **-rot0 \<real\> (0)**

  Rotate around an angle initially (90 degrees makes sense)

- **-T \<string\>**

  Plot a title in the center of the wheel (must be shorter than 10 characters, or it will overwrite the wheel)
