Dear Balaji,
Thank you very much for your help. I have made such a stupid error.
Best regards,

hai ! Catein Catherineyou load your prmtop fileand then give .mdcrd file and in vmd in the determine file type you give "Amber coordinates with periodic box "and load it and see your problem is solved all the best ! balajiUOM

Dear Sir/madam, I am trying to repeat the md simulation for DNA with explicit water. I downloaded the prmtop, in files and do the min1, min2 and md1, md2 calculations according to the tutorial one. The jobs finished without error message. However, when I try to open the mdcrd files with vmd, I found all the atoms becomes scattered lines. Should I view the conformational changes in the mdcrd file with vmd? If yes, did I do anything wrong for the calculation? At the end of the md2 out file, the following results were obtained.
