[AMBER] extracting selected lipids from bilayer

Dear Sir,

I have simulated double bilayers (two bilayers - total of four monolayers). 

I would name each layer with L1, L2, L3, and L4. 


Layer one (L1) comprise lipid numbers from 1 to 64,
layer two (L2) comprise  lipid numbers from 65 to 128,
layer three (L3) comprise lipid numbers from 129 to 192 and
layer four (L4) comprise lipid numbers from 193 to 256.

What I want is to extract out only the L1 (lipids from 1-64) from each frame from the whole trajectory. 

How I can  achieve this using cpptraj or ptraj?

I would appreciate  any help related to this.


Many thanks in advance.
