ANNOUNCEMENT - DSC v1.2
This version has minor improvements suggested by the monitoring
of web usage over the last month.
DSC - Protein Secondary Structure Prediction
I am pleased to announce the updating of our web site for
the prediction of protein secondary structure.
Two prediction modes are available:
1) Given a single sequence. A multiple sequence alignmentt
will be formed and DSC used to predict secondary structure.
2) Given a multiple sequence alignmnet. DSC will
use this alignment to predict secondary structure.
The advantages of DSC are:
1) It provides state of the artaccuracy.
DSC has a prediction accuracy of 70.1% on a
standard set of 126 proteins. This was not significantly different
from PHD, a popular prediction method. For medium length sequences
DSC was more accurate than PHD, and combining DSC and PHD produced
a prediction method more accurate than either.
2) It is free. There is no charge for using DSC.
3) The C source code is available. This would allow you
to run DSC on your own system if you had confidential sequences.
DSC is based on simple linear statistics. A paper on the
scientific basis of DSC was published in Protein Science:
