Re: [AMBER] Error during action on loaded multiple trajectory in cpptraj 15

Is 17500 the total # of input frames?

I'll have to try and reproduce this behavior before I can figure out what's
going on. It may be because after stripping all the water, each system
looks the same. In that case (and if you need each system split by
'trajin') you could achieve this with a combination of 'createcrd' and
crdout, e.g.

strip ...

createcrd MyCrd

crdout ura0_SPC.crd crdframes 0,2500
crdout ura1_SPC.crd crdframes 2501,5000

etc.

In the meantime I will try to figure out why you're seeing the behavior
you're seeing. Thanks.
