I fully agree, I suggest adding the steps for using the format you have developed directly to the LaTex document, based on the already provided code for creating synthetic data (the source for the LaTex document is located at: https://github.com/bio-brillouin/HDF5_BLS/tree/main/guides/Library_Test). 

The way I thought about the newsletter is, as you propose, to put the minimal amount of information to catch people’s interest, and then send them a unified PDF (testing HDF5+testing Zarr+how to use the treatment package) with essentially a tutorial that first presents a replicable example and then opens to an integration in existing codes to get an initial feedback. 

For the newsletter, I can technically wait as long as I want but because the deadline for abstract submission to BioBrillouin falls on October 1st, I think it would be best not too wait too long either (although most people might not need the reminder). I was therefore thinking of sending the newsletter by the end of the week. Since we’ll then send people the PDF, this would buy at least 1 and potentially 2 weeks for fixing the bugs you have found in your code and writing your steps to test your solutions. 

Following Kareem’s idea, I’ve put together a list of questions (cf. document attached) we could build on to ask people for feedback. Don’t hesitate to modify it! 

Best,

Pierre
