File type specification:

Various data file type icon Various data file type

The ptrack file extension is associated with SAM (Sequence Alignment and Modeling system).

The *.ptrack files are created by predict_track. The .ptrack files contain secondary structure (or other second alphabet) predictions for a given sequence based on a primary sequence model, and databases of primary and secondary structure for a group of sequences.

The Sequence Alignment and Modeling system (SAM) is a collection of fsoftware tools for creating, refining, and using linear hidden Markov models for biological sequence analysis.

The model states can be viewed as representing the sequence of columns in a multiple sequence alignment, with provisions for arbitrary position-dependent insertions and deletions in each sequence. The models are trained on a family of protein or nucleic acid sequences using an expectation-maximization algorithm and a variety of algorithmic heuristics. A trained model can then be used to both generate multiple alignments and search databases for new members of the family.
