viral biodiversity in rodents
DESCRIPTION
I was invited to give a short presentation about the tools that I use for my research in Cayenne, French Guiana (sickle, velvet, digital normalization (khmer), krona, awk and others).TRANSCRIPT

Collect biological samples
Isolate the viruses
Sequence viral cDNA
