+ <strong>Feature Filters</strong>
+ </p>
+ <p>This section is optional, and allows one or more filters to be defined for each feature type.
+ <br>Only features that satisfy the filter conditions will be displayed.
+ <br>Begin with a line which is just STARTFILTERS, and end with a line which is just ENDFILTERS.
+ <br>Each line has the format:
+ <pre>featureType <em><tab></em> (filtercondition1) [and|or] (filtercondition2) [and|or]...<br></pre>
+ The parentheses are not needed if there is only one condition.
+ Combine multiple conditions with either <em>and</em> or <em>or</em> (but not a mixture).
+ <br>Each condition is written as:
+ <pre>Label|Score|AttributeName condition [value]</pre>
+ where <em>condition</em> is not case sensitive, and should be one of
+ <ul>
+ <li><em>Contains</em> - value should contain the given text (not case sensitive); example <em>clinical_significance contains Pathogenic</em></li>
+ <li><em>NotContains</em> - value should not contain the given text</li>
+ <li><em>Matches</em> - value should match the given text (not case sensitive)</li>
+ <li><em>NotMatches</em> - value should not match the given text (not case sensitive)</li>
+ <li><em>Present</em> - specified attribute is present on the feature (no value required); example <em>CSQ:SIFT present</em></li>
+ <li><em>NotPresent</em> - specified attribute is not present on the feature (no value required)</li>
+ <li><em>EQ</em> - feature score, or specified attribute, is equal to the (numeric) value</li>
+ <li><em>NE, LT, LE, GT, GE</em> - tests for not equal to / less than / less than or equal to / greater than / greater than or equal to the value</li>
+ </ul>
+ A non-numeric value always fails a numeric test.<br>If either attribute name, or value to compare, contains spaces, then enclose in single quotes:
+ <em>'mutagenesis site' contains 'decreased affinity'</em>
+ <br>Tip: to see examples of valid syntax, first configure colours and filters in Jalview, then <em>File | Export Features</em> to Textbox in Jalview Format.
+ <br><em>Feature filters were added in Jalview 2.11</em>
