Select/Hide Columns by Annotation

The 'Select/Hide by Annotation' window allows columns to be selected or hidden according to annotation rows on the alignment. The dialog box is opened via "Select→Select/Hide Columns by Annotation...", and different filters are presented dependent upon the data shown in the selected annotation row.

If an annotation with numeric values is selected, the threshold filter option is activated. For other types of annotation, use the text box and secondary structure check boxes (right). The radio buttons at the bottom of the dialog specify the action applied to columns matching the query.

• Search Filter
  • Enter text or regular expressions in the text box to activate the 'Display Label' and 'Description' options.
  • Selecting the description or label options will activate the filter, and any matching columns will be highlighted or hidden.
• Structure Filter
  • Select the checkboxes to filter by secondary structure type.
• Threshold Filter
  • This filter is only activated for annotation which contain numeric values
  • Select whether to filter the alignment above or below the threshold.
  • Change the threshold value with the slider, or enter it in the text box.
• Actions
  • 'Select' (the default), selects columns matching the query settings.
  • 'Hide' causes matching columns to be hidden.

Hit 'Cancel' to restore the alignment view to its previous state before any filtering was applied.
