Hi Folks: Some questions have been asked this past week about a FASTA segmenter. I wanted to point anyone interested in such a tool over to http://scalableinformatics.com/segment.html . One corner case is for huge output files. Currently they are built in RAM. This could cause problems for things like splitting large databases where the output is comparable in size to main memory. It will work, it will just swap rather hard. This shortcoming will be addressed in future releases. Please send me a note if you pull it down and use it. Real documentation is forthcoming.
