Dear VMD Users

I am working on G-protein coupled receptor simulations.

I would like to analyse teh helical motions of the extracellular part of the
protein.

For that, I would like to collect the c-alpha co-ordinates of X & Y from the
center of the extracellular part of the each helix (not from the center of
the whole protein) by making Z as zero.

Is there any script available in VMD to do the same or if anyone performed
similar task kindly advice.

Many Thanks
Balaji
