The program is written in Microsoft Access 2 and the full source code is available in the program.
The software is made available in the hopes that other researchers can modify it for their own needs.
If you wish, you can download the software.
NOTE
I have changed my mind about one aspect of the program. Splicing mutants that are complex (eg, have more than one mRNA) are recorded in both the tables related to splicing (tables SPL_CAUSE and SPL_EFFECT) and complex mutations (table COMPLEX). I think this is WRONG. I would suggest just keeping the information regarding splicing mutants in the tables related to splicing (tables SPL_CAUSE and SPL_EFFECT).
DISCLAIMER
The program is fairly complex and modifications should not be attempted by someone with little programming experience. I can answer some basic questions, but I cannot "walk" you through modifications of the program.
