LoopViewer╩╩╩╩╩╩╩╩╩╩╩╩╩╩╩╩╩╩╩╩╩
is a tool for drawing RNA secondary structures in
molecular biology.
LoopViewer is a subset of a more complete RNA structure
drawing and editing program, LoopDLoop. As of this writing,
the complete LoopDLoop is still under development.
LoopViewer has two viewing modes:
Ñ The drawing view which converts your sequence
to a display of the secondary structure.
Ñ The text edit view where you can read in or type in the
text of an RNA sequence with base pairings.
The current versions of LoopViewer and LoopDLoop will
not run on Mac SE or Mac Plus machines. They require
Macintoshes with math coprocessors, color is an option
but not required.
Input Data:
LoopViewer accepts data in three forms:
Ñ CT (connect) file format, as produced by Micheal Zuker's
MulFOLD programs and others. This CT format make contain
multiple RNA molecules. All molecules are drawn.
Ñ A string of sequences followed by a matching string of
pairing characters. Each line contains only nucleotides or
only pairings. The base pairings are denoted by matching
parentheses "()" and brackets "[]".
Ñ The format for Gary Olsen's LOOPSOL program. This is a
sequence of nucleotides with base pairings interlaced among
the nucleotides denoted by matching parentheses "()" and
brackets "[]".
In all cases, the text style of nucleotides, including color, size,
font and text face will be copied into the secondary structure
drawing.
