Welcome to the ct2dot Web Server

The ct2dot server converts a CT file into a dot bracket file, which is an alternate structure file format. Only one structure in a CT file can be converted at a time; if more than one dot bracket file must be made, this server must be run once for each structure. Note that the dot bracket output from this server can be used as input in the dot2ct server to regenerate that part of the CT file.
