I know that people on this mailing list are mostly dedicated to work with microarray data, but real-time PCR (QPCR) is also a part of transcriptome analysis - so here is my question: Does anyone know of any R-package to work with Q-PCR data that is capable of reading sds files or its exports and use a delta-delta Ct method or any other... Thank you for any information, Matjaz _____ Matjaz Hren National Institute of Biology Dept. of Plant Physiology and Biotechnology Vecna pot 111 1000 Ljubljana SLOVENIA www.nib.si phone: +386 1 423 33 88 fax: +386 1 257 38 50 _____

Hi Matjaz, the package 'prada' from Bioconductor includes some functions for this purpose. Best Markus
