Dear VMD users

Recently, I came across the below link and tried to calculate secondary
structures for trajectory frames using the tcl script given in the link.


The script uses vmd for calculation.

The first step works fine and i got the output ss_traj.dat.

In the second step, it shows that using ss_plot it converts ss_traj.dat
into post script file.

While using command ss_plot <ss_traj.dat>, i'm getting error as
ss_plot command doesnt found.

I copied & pasted the source code for ss_plot.c in the working directory,
still i'm running out of the same problem.

Kindly advice.

Many Thanks
