Hi Marcelo,
First of all, thanks for using PyPLN in this early stage and helping us sort out all this problems.
I think you document has triggered one of our old bugs, which we have already fixed, but we still lack a way to force a rerun of the analysis through the interface, and this message is a terrible way of saying that the processing might have stopped (this is known issue:
https://github.com/NAMD/pypln.web/issues/46, we are working on it).
I forced all the analysis on your documents to rerun. This may take a while to finish, but if you visit the document it should have at least some analysis ready.
It may also be the case that some documents (and maybe this one you've pointed to) have triggered unknown bugs, and they will show the same message again. If that is the case please let me know, and we will figure out which bug this is.
Again, thank you very much for using PyPLN, and even more for helping us iron out bugs at this stage. Also, please don't hesitate to ask more questions if you have them.
Sincerely,
Flávio Amieiro
