[AMBER] Problem with PCA projection

Hi all,

I am having a trouble when performing projection of component trajectories
on the eigenvectors calculated from combined trajectories. I cannot specify
the starting and ending frame number for projection.

[crdaction avg-traj projection PEP modes evecs.dat beg 1 end 10
:1-313.CA *crdframes
10001 , 20000* out PEP.dat]
    PROJECTION: Calculating projection using eigenvectors 1 to 10 of
evecs.dat
        Results are written to PEP.dat
        *Start: 1 Stop: Final frame*
        Atom Mask: [:1-313.CA]
        Mask [:1-313.CA] corresponds to 313 atoms.
 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% Complete.

When I add 'start' and 'stop'

  [crdaction avg-traj projection PEP modes evecs.dat beg 1 end 10
:1-313.CA *crdframes
start 10001 stop 20000* out PEP.dat]
    PROJECTION: Calculating projection using eigenvectors 1 to 10 of
evecs.dat
        Results are written to PEP.dat
        *Start: 1 Stop: 20000*
        Atom Mask: [:1-313.CA]
        Mask [:1-313.CA] corresponds to 313 atoms.
 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% Complete.


Could anyone tell me how to make cpptraj understand the specific frame
number for projection.

Thanks
kat
