Table 3 Average Scoria execution times for various file I/O tasks, running in three different Python environments

From: Scoria: a Python module for manipulating 3D molecular data

Action Python with NumPy/SciPy Python without dependencies PyPy (incompatible with dependencies)
Save PDB 0.0055 ± 0.0010 0.0085 ± 0.0016 0.0036 ± 0.0043
Load PDB (without calculating bonds by distance) 0.0104 ± 0.0010 0.0643 ± 0.0028 0.0198 ± 0.0163
Save PYM 0.0024 ± 0.0013 N/A N/A
Load PYM 0.0008 ± 0.0004 N/A N/A
  1. Saving and loading PYM files requires NumPy and so could only be tested in environments with that module installed (“N/A” otherwise)
