Dear all:
I'm trying to calculate kinks within alpha helices using gmx bundle. I
specify 4 Ca atoms from the helix top, bottom and kink separately in the
index file. And, I've used the option -na 1. But I keep getting the results
shown below.
@ title "Kink angles"
@ xaxis label "Time (ps)"
@ yaxis label "(degrees)"
@TYPE xy
0 -nan
500 -nan
1000 -nan
1500 -nan
2000 -nan
2500 -nan
3000 -nan
3500 -nan
4000 -nan
4500 -nan
5000 -nan
... ...
Does anyone know what "-nan" implies? Any advice would be appreciated,
thanks in advance.
Best,
Wei-Hsiang
