Welcome to D-ORB!


Create
Get the structures and classifiers of input sequences
Query
Predict the Rfam-derived families of input sequences
Mutate
Generate variant sequences of an input sequence
Draw
Get the picture of a specific NCM

Here's a quick guide to know which tools to use and how to use them in order to answer some questions.

If you have: And want to: You can:
A set of sequences sharing a common function -Identify distinctive ORBs
-Generate classifiers
-Generate a consensus structure
Use the Create tool
Two sets of sequences, positives and negatives, where the positives share a common function lacking in the negatives -Identify discriminant ORBs
-Generate classifiers
-Generate a consensus structure
Use the Create tool, and check the "Submit negative sequences" option to incude the set of negatives
One or more sequence(s) -Predict the Rfam-derived families of these sequences Use the Query tool to run the sequence(s) through our Rfam-derived classifers
A wildtype sequence -Generate muted variants Use the Mutate tool
The need -To get the picture of a specific NCM Use the Draw tool
Curiosity -Browse our Rfam-derived families Browse our Rfam-derived families using the gray button on top right
One or more sequence(s) -Categorize each sequence with resulting classifiers Use the "Categorize" button on a result page
One or more sequence(s) -Generate secondary structures for each sequence, matching either a D-ORB structure or ORBs Use the "Fold" button on a result page
A wildtype sequence -Identify mutants that lose important ORBs Use the "Mutagenize" button on a result page
