Hi there,

If you want a more comprehensive list of Picard commands and parameters you can refer to the Javadoc:

http://broadinstitute.github.io/picard/javadoc/picard/index.html

Or the Picard metric definitions:

https://broadinstitute.github.io/picard/picard-metric-definitions.html

And the FAQ:

http://broadinstitute.github.io/picard/faq.html

Ultimately if you want to have this offline and accessible through a database you can download it with:

wget --no-parent --recursive --level=inf --page-requisites --wait=1 http://broadinstitute.github.io/picard/javadoc/picard/index.html
