SKILL.md 摘录

Loading Alignments

Goal: Read an MSA file and inspect its dimensions.

Approach: Use AlignIO.read() specifying the file and format.

Column-wise Analysis

Goal: Analyze alignment content column by column to assess composition, conservation, and variability.

Approach: Use column indexing (alignment[:, idx]) and Counter to examine character frequencies at each position.

Gap Analysis

Goal: Quantify gap distribution across sequences and columns to identify problematic regions or sequences.

Approach: Count gap characters per sequence and per column, then identify positions exceeding a gap fraction threshold.

适用场景

  • 适合在parsing 或 manipulating multiple sequence alignments时使用。

不适用场景

  • Do not rely on this catalog entry alone ,用于 installation 或 maintenance details。
