loopDloop is a Macintosh software tool for drawing RNA secondary 
structures in molecular biology.    

NOTICE:  This is an early, unfinished version of the program.   
Expect it to fail in various ways.  This release is made 
available to those who wish to test and comment on its future 
development.  This release will expire on a date indicated in
the About dialog. 

LoopDloop is an secondary structure drawing program - it is NOT
an RNA folding program.  The base pairings (i.e. secondary 
structure) are defined by the user, not predicted by the 
program.  LoopDloop then allows the manipulation of the 
resulting secondary structure representation.

loopDloop accepts data in three forms: CT (connect) file format,
a file with interleaved sequence and pairing character lines,
or the format for Gary Olsen's LOOPSOL program.

The current version of loopDloop will not run on Mac SE or Mac
Plus machines.  It requires Macintoshes with math coprocessors.
Color is a useful option but not required.
You can obtain new releases of this software thru anonymous ftp 
to ftp.bio.indiana.edu, in folder /molbio/loopdloop/, as 
loopdloop.hqx, or using Internet Gopher to ftp.bio.indiana.edu, 
in a folder called "IUBio Software+Data/molbio/loopdloop/".

Comments, bug reports and suggestions for new features (see

LoopDLoop was started Winter of 1989 as a modern tool with a
good user interface, for drawing and editing RNA secondary
structure.  A preliminary version has been in limited distribution 
for a few years.  A subset of loopDloop, lacking the editing 
operations, was released as LoopViewer in the Fall of 1990.
LoopDLoop has been converted to a MacApp-based program.

4 August 92, v 1.2a57 -- First public release of loopDloop.
