- <p>
- The <strong>Calculations Dialog</strong> (shown above) is opened via
- the <strong>Calculations→Calculate Tree or PCA...</strong>
- menu entry.
- </p>
- <p>
- It allows you to select the type of alignment analysis calculation (<a
- href="pca.html">PCA</a> or <a href="tree.html">Tree</a>), and the
- sequence similarity score model that will be used to perform the
- analysis.
- </p>
- <p>
- <strong>Adding additional score models</strong><br />Jalview can
- import substitution matrices in both <a
- href="http://www.genome.jp/aaindex/aaindex_help.html">AAindex</a>
- and NCBI format (see e.g. <a
- href="http://ftp.ncbi.nlm.nih.gov/blast/matrices/">ftp://ftp.ncbi.nlm.nih.gov/blast/matrices/</a>).
- In Jalview 2.10.2, the easiest way to import new models is to drag
- the score model file onto any alignment window. See the <a
- href="scorematrices.html">Substitution Matrices Documentation</a>
- for more information.
