Arka provides a nice GUI for the gp package of command-line utilities for manipulation and display of DNA/RNA/protein sequences, the WU-BLAST and FASTA program families, and additional graphical tools for various aspects of sequence analysis (e.g., GC plots and 3D graphs). It provides editable and saveable windows for standard input, output and error, and a dialog for any command-line program with specifications in a configuration file.
Release Notes: Interface added for the FASTA and WU-BLAST families of programs. A bug in the search and replace dialog fixed.
Release Notes: New additions include a manual page and command line options for specifying input and output files. Some memory leak control routines were also added, and these were used to fix some memory leaks. Some memory protection faults in the programs dialog which made this dialog unusable were corrected. Other minor bugs were fixed.
Release Notes: A fix for another bug in the preferences dialog, and a new search/replace dialog which supports regular expressions.
Release Notes: This release fixes a bug in the preferences dialog, improves program descriptions, includes a GUI for several GNU utilities (grep, find, wc, nl, tsort, and paste), and now supports user-created shortcut keys.
Release Notes: A sequence editor was added. Some major bugs were fixed. A feature freeze has been put into effect, and the project is in a beta stage now.
