text: user1075: Is it possible to find out the PacBio chemistry from the PacBio Sequel BAM's header? E.g. whether it was produced with P5-C3 or P6-C4? I checked mine but I haven't found it but maybe it's hidden in one of the tags whose meaning I don't know yet, like SEQUENCINGKIT=100-861-800?
  
  user294: According to PacBio Sequel BAM format manual, you can find information on the chemistry version in the header entries @RG (read group), tag DS (description), entry BASECALLERVERSION . 
  In case of future very PacBio-specific questions, you can contact Liz Tseng on Twitter (@magdoll), one of the most responsive PacBio developers. They also have a dedicated SeqAnswers forum, which is directly monitored by them and you are very likely to get a fast and accurate answer.
