I am a newbie experienced in bioinformatics, linux and python programming interested in cancer genomics. I don't have any funding at the moment to sequence cancer genomes from patient samples and publish results. So I am wondering if it is a good idea to download cancer genomes from https://tcga-data.nci.nih.gov/tcga/ or some other source (let me know if you are aware of any), perform some preliminary analysis using different variant calling algorithms, publish some short papers and then apply for funding. I have access to several clusters and supercomputers for processing data. Thank you.
I would agree with Giovanni that your best bet is to offer your services to a group actually working in cancer genomics and start from there.
I have found that a good way to market your services is to share your knowledge via classes for local researchers involved in such work. A cancer center, department, or lab/division will typically jump at the chance at free instruction and education.
