Hamid R. Eghbalnia, Liya Wang, Arash Bahrami, Amir Assadi, John L. Markley, "Protein energetic conformational analysis from NMR chemical shifts (PECAN) and its use in determining secondary structural elements", Journal of Biomolecular NMR,2005 May;32(1):71-81.


PECAN is an automated tool for probabilistic secondary structure determination of proteins. The input format is NMRSTAR 2.1 (BMRB) format, and. the result will be returned via email in a couple of minutes.

Description of PECAN input and output files can be found below.

Input file (NMRFAM-Sparky two-letter-code: n6)
