Graph type [x11]:
You will see a window that looks like this:
The bars across the top represent areas where transmembrane segments are predicted. Taken in combination with the results from pepinfo, we can see that there may be seven transmembrane helices in this protein. This corresponds well with both the SwissProt entry for this sequence (opsd_xenla) and with some information we will gather about patterns and profiles in the next chapter.
There are various other programs you can use to analyse your peptide sequence - to find out what is available, try rerunning wossname as we did in the first chapter.
