This page lists the changes made to Area Fill -- enhancements and bug fixes.

Version 1.43 Windows November 17,2007

A problem was fixed in the Windows version. 1.40 on Linux and Solaris have no problems.

Version 1.40 March 7,2007

This is the first version that uses the QIS Library in AreaFill for faster processing.

Added perimeter calculations for Molecular Imprints.

New XML output support.

More precisions in the output of the percentage description per Skyworks request.

New program afill2tiff (UNIX and Linux only).

Version 1.18 August 3, 2006

The routine that explodes arrays has been rewritten to handle extremely large AREFs by precomputing which array elements fall into the window under consideration. For a 50,000 x 50,000 array, the processing time was reduced by 360X due to this precomputation.

Additional algorithmic improvements were made to the exploder resulting in a 3X improvement in throughput for dense files.

Version 1.15 June 19, 2006

Corrected an error in the tiling output text where data fields would run into each other.

automatic partioning of the database is made the default when no tiling arguments are specified on the command line. Previous to this, the default was no automatic partioning which resulted in slow execution times for larger files. (automatic partitioning command line argument is: +nclip:1,1)

Version 1.14 June 16, 2006

Output is now directed to the specified file. Previously always went out to the log file.

Version 1.13 June 15, 2006

Adds a tiling option so that the use can specify a tile (X,Y) which will be tiled across the extents of the selected window. The output is saved in tabular format.

released as a Linux 32 bit binary. Tested on Red Hat Enterprise 4 but should run on other versions of Red Hat Linux.
