Debug atom

Good afternoon. Is there any way to get more detailed information from atom?
I am trying to execute the command atom reachables -l ts -s reachables.json .
In the console output, I get "Generating data-flow dependencies from atom. Please wait ...", but the file is empty. I've been monitoring RAM and its operation doesn't take up all of it. The program itself creates the app.atom file itself with a volume of 200 megabytes, but when the iteration of creating the reachables file begins, it ends.
