Dear Sir:
     How can I use amber force field to calculate protein.
     I think that I should do this according to the following 3 steps.
    1) I should generate a psf file and a coord file. Which top file should be used to gererate the psf file? Where can I download the topfile? What type is the coord file?? Is PDB OK??
    2) I should have a amber parameter file. Which parameter file should I choose? Where can I download the parameter file??

    3) I should modify the configure file acoording
       then I run NAMD.

    So, there are so many questions before I excute the 3rd step. Please help me and answer the questions in detail! Thank you very much??
