Dear list,
I wonder why the command measure sasa does not give consistent results
which should be independent whether the protein is rotated.
For example, I loaded protein with PDB code 1AUQ.
Then, I calculated the SASA of the entire system:
measure sasa 1.4 [atomselect top all]
10260.4560546875
I rotated the system by 30 degrees around the y-axis:
[atomselect top all] move [trans y 30]
And calculated the SASA again:
measure sasa 1.4 [atomselect top all]
10272.072265625
After rotating the system, the SASA was 11.6 A larger. Any idea why the
result is not consistent?
Thanks,
Gianluca
