[Chimera-users] TM tendency hydrophobicity scale

Hi Shyam,
After skim-reading the paper and trying the “TM tendency” scale on a few different structures, it seemed worthwhile to add.  I was interested in trying it myself.  :-)

Additions are in the “hydrophobicity” page:
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/hydrophob.html>
… and the list of example attribute-definition files:
<http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/defineattrib/defineattrib.html#examples>

Let me know if there’s anything about the credit to you that you’d like changed.  I included a middle initial for specificity, not knowing if there are other people with your same name.  Thanks for the contribution!
Best,
Elaine
