boolean error

[Samuel Little]

Hi everyone,

A colleague of mine is picking up dedalus and it getting this error when running a script. The code we use is a bit old and it only runs o dedalus v2 so far, which is what they have installed. Does anyone know a fix?

Samuel,

     To me it looks like something is incorrectly set in their dedalus.cfg file.

In particular, in the "analysis" section of that file, it looks like the value of FILEHANDLER_PARALLEL_DEFAULT is set incorrectly.  I believe that it needs to be a boolean, and it looks like they have a different value.
