RNAstructure 6.0 (09/21/2017)
- Calculations are now performed in "parallel mode" -- i.e.
threads. (This was also true of the previous
native Windows Interface, but not the Java Interface.)

clicks and gaps at beginning and end of files • Increased
shorter sounds • Added alert sound for invalid characters •
beginning of "C" to sound less like "T")

structure analysis workflows for predicting single structures,
bimolecular structures, and structures common to two or more

edits structure drawings and outputs publication-quality
drawings. This also can edit the underlying base pairing
structure and sequence.

calculations because the
progress indicator is now displayed inside each parameter
of as a separate window disjointed from the main application).

newer OS and Java versions.

either not set or it
points to an invalid location. Now an informative message is
program startup. Previously no message was shown until the

DATAPATH, at which time a less informative message was
- Fixed bugs in the Java GUI:
- Printing structures and images did not work (only blank
pages were produced).
GUI would crash on startup if the splash window (or any
window) was still open when the main application window was
- Typing a non-existant file name in the Open Sequence
window caused the program to freeze.
- Selecting a file with an upper- or mixed-case extension
resulted in a "File Not Found" error.
- The main menu became unresponsive when the toolbar was
moved to a floating window.
- The Java GUI DotPlotDialog window crashed when
postscript legend colors under some circumstances (such as
colors were specified as doubles instead of ints (e.g. 10.0
Version 5.7 (Released 12/4/2014)
- Fixed a bug in the Windows GUI for bimolecular folding where
internal loops were intermittently being forbidden.
Version 5.6 (Released 7/31/2013)
Windows GUI now runs in parallel on multicore computers for
lowest free energy structures, calculating partition
calculating free energy changes, oligoscreen calculations, and
- Fixed a bug with reading HMM
alignment parameters for Dynalign calculations in the Windows
was causing the program to crash for Dynalign calculations.
Version 5.5 (Released 4/5/2013)
- Fixed bug in JAVA GUI where opening .seq files from disk
would sometimes fail.
Version 5.4 (Released 8/2/2012)
- Added TurboKnot function to TurboFold module.
- JAVA GUI overhauled to appear more native-like on Mac and
- Windows GUI updated to Windows 7 standards.

nothing, from the menus of the Windows GUI.
bug in JAVA GUI where the partition function bimolecular
sometimes overwrote its second input sequence file, rather
the desired output name.

sanity checks sometimes failed.
- Fixed a bug in the Windows GUI, where pressing the F1 key
resulted in a "Failed to Launch Help" window in Windows XP and
