Dear Francesco, The recommended size for software packages is less than 2 MB on disk as you noted from http://wiki.fhcrc.org/bioc/Package_Guidelines#size-requirements Data files in the range of 10 ~ 30 MB will need to be built into a separate data package and would typically go into our experimental data package repository or into the Metadata category if its related to Annotation, CDF and Probe data http://bioconductor.org/download/index.html A typical user of your software package would probably not need the large data files for their application and hence we would like to maintain them as separate packages. If you are planning to build an annotation data package please get in touch with Marc Carlson (mcarlson at fhcrc.org) and he should be able to guide you through the process. If your are building an experiment data package, I can help you put one together. Once you have created your packages, please register at http://tracker.fhcrc.org/roundup/bioc_submit/index and create a new issue on the tracker to submit your package Nishant (I am forwarding the response to your question to the Bioconductor mailing list so that this information is available to other people searching the mailing list archives) Quoting Francesco Favero <francesco.favero.bioc at="" gmail.com="">: > Dear Nishant, > > I have done a package to cross the miRNA and gene expression microarray > data, I would like to upload it but it 30 Mb big instead of the 2 Mb > required from the "Package Guidelines".
