Julia Doh and coworkers prepared detailed methods papers for publication in Bio-protocol on using the VIPER tag. We were interested in working with Bio-protocol and Editor Dr. Zhao Chen because this is an open-access journal. We support Bio-protocol's mission, which is to "make life science research more efficient and reproducible by curating and hosting high quality, free access protocols". You can find our methods papers in the current issue (Bio-protocol November 2019).
