Hi, Now it seems everything is working. First I want to thank everybody for helping on this project. I know it is not gonna be easy, but I think it will be rewarding. Since I'm just an amateur programmer I would like to delegate code writing. In order to delegate in the best way, I would like you to tell me about your coding and/or bioinformatics skills and available time. Then we will discuss how to go on with this. I start with me: I know some Python, C and VB, but I'm not very good (OOP is NOT my strong point). My daytime job is at seed company in Argentina doing IT and database curation, where I use some Python. I don't code well but I have a very clear goal regarding GUIBLAST. PS: English is not my first language, so correct me or tell me if something is not clear enought. -- Best regards, //=\ Sebastian Bassi - Diplomado en Ciencia y Tecnologia, UNQ //=\ \=// IT Manager Advanta Seeds - Balcarce Research Center - \=// //=\ Pro secretario ASALUP - www.asalup.org - PGP key available //=\ \=// E-mail: sbassi@genesdigitales.com - ICQ UIN: 3356556 - \=// http://Bioinformatica.info
