[AMBER] Does Parmed tiMerge accept all ambmasks?

Hi;

    I am trying to use parmed’s tiMerge utility to setup a TI calculation. tiMerge works fine when the masks are all full amino acids, e.g.

tiMerge :1-5 :6-10 :1 :6

But if I try the following, I get an error:

tiMerge :1-5 :6-10. ‘:1 & !.CA,C,N,H,O’ ‘:6 & !.CA,C,N,H,O’

The error is:

Action tiMerge failed
                TiMergeError: The number of nonsoftcore atoms in mol1mask and mol2mask must be the same. Check the masks. If these look correct try using a larger tolerance.

Is tiMerge supposed to be able to interpret complex mask expressions beyond residue numbers?

Thank you in advance;

-Sergio
