Hi All, I am a novice programmer in Bioperl. For my project, I have to parse the Genbank files and make a dataset. But I am facing the problem while mapping the mRNA and CDS of the Alternative Splicing genes. Whether there is any special module in Bioperl, which will extract the Alternative Splicing genes from the Genbank file, or how we can parse the Alternative Splicing gene information from the Genbank file using Bioperl. Example of Alternative Splicing gene entry : http://www.ncbi.nlm.nih.gov/nuccore/1145692 Thanks, Amrita
