Protein Contact Map Prediction

RaptorX-Contact is a web server that predicts contact map of a protein sequence without using any templates. It applies an ultra-deep learning model to predict contacts and works particularly well on proteins without many sequence homologs. Our deep learning method has a very high accuracy by learning contact occurrence patterns. This server also predicts the tertiary structure of the input sequence by feeding the predicted contacts into CNS as distance restraints, but without using any templates. RaptorX-Contact was ranked 1st in contact prediction in the worldwide protein structure prediction (CASP) competition round XII. See here for a ranking list published by the CASP12 official assessors.

Job policy
To maximize the utility of the server to the community at large the following limits on job submission for each user are enforced.
  • Please submit up to 50 protein sequences (in the FASTA format) in a batch for prediction. If your email box cannot receive a large attachment file, please submit a SMALL number of sequences in a batch. Otherwise the result package may be too big to be received.
  • Please SAVE the assigned JobID for retrieval of job results, especially when an email address is not provided in submission.
  • Each user can have no more than 500 sequences pending prediction at any time.
  • Should you have a special project that requires more resources, please contact us to inquire further.
