convert json back to msh

[lskatz]

Hi, I was wondering if you implemented a way of creating a .msh out of a JSON file. I want to alter my mash sketches a little bit and then convert them back to something that Mash can use. Or also, it would be useful to know if it can read the JSON. Thank you!

I would also be interested in this feature. For example, imagine a situation where you sketch a large collection of genomes into db.msh. Now you want to do all-vs-all on a subset of db.mash. You can't. Instead of you have to sketch the specific genomes again to subdb.msh and then you can mash dist subdb.msh subdb.msh. It would be very convenient if it was possible to dump your specific sketches to subdb.msh directly from db.msh. Something like mash dump -l yourSketchList.txt db.msh > subdb.msh. Alternatively, it could be dealt with by constraining your mash dist to specific sketches, e.g. mash dist -c youSketchList.txt db.msh db.msh > results
