Dear Nima,

In addition to the suggestions made by Giuseppe I would recommend:

I-Tasser

https://zhanglab.ccmb.med.umich.edu/I-TASSER/

This program requires nothing but the FASTA form of the primary sequence of your protein.

PS. You need to register (just give an e-mail address where you want to receive the result). A little warning: the result can take a couple of days (depending on the size of your protein). Last but not least: you need a program to visualize the result (Chimera for example).

Good luck!
