[Chimera-users] Reading a data set from a text file

[Kyaw Zeyar Myint]

Hi Dr. Meng,

I am sorry for my vague question.

I have a table of numbers in a text file and I'd like to read in  
those numbers and convert them into cartesian coordinates so that  
they can be displayed as a surface in Chimera.

If you could give me some suggestions on how to do it, I'd really  
appreciate it.

Thank you,
Kyaw
