Inconsistent Output Using Standalone Vs. Web Interface

[etleyden]

When generating an amino acid composition via the web interface, I am able to successfully generate results for this file. The protein sequence on line 39 however (which I was only able to identify after refactoring "Error: The input sequences contain non-natural amino acids. Kindly check the sequence" to return more useful information when getting the composition of many sequences) seems to be the issue when using pfeature_comp locally, as it contains some non-natural amino acids.

I would like to be able to resolve the correctness of either result.
