[chimera-dev] (no subject)

[Elaine Meng]

Hi Kavya,

(1) this is exactly the same problem you had before when trying to follow my example, and we had already solved it by figuring out you had to use the newer Chimera!!  The emails are shown below.  Please do not keep asking the same question.

(2) If you want to ask questions you should put some useful information in the email subject line.  “no subject” is not useful.

It was hard to see if you entered exactly the same “mm” command as in my example (needs to be exactly the same, with colon : dot . and no extra spaces), but it you did, maybe you are using an old version of Chimera that interpreted the command differently.  I only started Chimera and entered those 5 exact commands to get the result I showed. Tested in Chimera version 1.11.2 and recent 1.12 daily build.
