Hi,

I have a box with multiple peptides in it.
When I run g_sas either on a single peptide or on all peptides I get different results with version 3.3 and version 3.3.2

1) On a single peptide (I chose 1 peptide for surface calculation and 1 peptide as the output):

with 3.3:
# g_sas -f ../traj1_12_1micro_System_dt100ps.xtc -e 100 -s topol33.tpr -o 
area1_33.xvg -n index.ndx
#
         0     1.05683     1.53052     2.58735           0

with 3.3.2
# g_sas -f ../traj1_12_1micro_System_dt100ps.xtc -e 100 -s topol332.tpr -o 
area1_332.xvg -n index.ndx
         0    0.973462     1.61389     2.58735           0

2) On all peptides (I chose ALL peptides for surface calculation and ALL
peptides as the output):

with 3.3:
# g_sas -f ../traj1_12_1micro_System_dt100ps.xtc -e 100 -s topol33.tpr -o 
area33.xvg
         0     35.3378     40.1608     75.4986           0

with 3.3.2:
# g_sas -f ../traj1_12_1micro_System_dt100ps.xtc -e 100 -s topol332.tpr -o 
area332.xvg
         0     37.7036     50.8631     88.5667           0

Am I doing something stupid or is it a bug?

Thanks,

Isabella
