I would like to suggest you assign hydrogen in H-C=C to HA. Then CM-HA,
CM-CM-HA are available. CT-CM-HA is still missing for parm94 and parm99,
you may use parameter of c3-c2-ha (45.9 117.3) in gaff instead.

PM
Please respond to

Dear Amber users:
I got a problem when I created the .top and .crd files for 1,9 decadiene
molecule. I assigned the 'CM' to carbon atom of the C=C double bond and
'HC' for all the hydrogens in the molecule. However when I tried to
generate .top and .crd files, the xleap reported that it could not find the
'bond' and 'angle' parameters for CM-HC, CM-CM-HC, CT-CM-HC, etc. My
questions are:
1. Did I assign the atom type wrong to the Carbon and hydrogen atoms?
2. What PARAMSETS should I use for 1,9-decadiene?
Thanks,
Yichen
