Incorrect hmmscan settings cause popen3 to hang rather than an error

[lguangyu]

I have manually assigned hmmscan in the config.yml file. Recently discovered that when it is pointing to a broken path, the call to exec_annotation will hang up forever at lib/kofam_scan/parallel.rb:28 rather than throw a file not found error.

I have the same issue with the current conda version. Any clue how to solve this? As it just hangs, no error, no message or anything...

Is there a near-future plan to resolve this issue? I am also at a loss on how to solve this.
