## OCCURRENCE

### In Sequence Editors - Primary Editor (ARB_EDIT4) and Secondary Editor

## DESCRIPTION

### This function can be used to Visualize Sequence Associated Information (SAI) in the Primary Structure and Secondary Structure Editor windows.

### Steps to use VISUALIZATION of SAIs in Primary Structure Editor:

1. Select SAI to be visualized from the SAI list (all SAIs present in the ARB Database).
2. Select the Color Translation Table (CTT) in the CTT list, if found. Or create one by pressing CREATE button. You can also copy the existing CTT and modify.
3. Once CTT is created, define desired colors (RANGE 0 to RANGE 9) for the respective characters in the selected SAI to paint as background of the sequence.
4. You can also change the COLOR RANGE by going to PROPERTIES->CHANGE COLORS AND FONTS menu.
5. Then, choose the visualization options. You can opt to visualize only MARKED species or ALL species in the primary editor.
6. Finally, be sure to check ENABLE VISUALIZATION check box.

### If Color Translation Tables were defined for each existing/displayed SAIs in the Primary Editor, one can navigate through different SAIs in the editor and visualize the same instantly. To enable this feature, AUTOSELECT SAI should be enabled in Visualize SAI window (VIEW->VISUALIZE SAIs menu).

### Sequence Associated Information can also be visualized in Secondary Structure Editor.

To Visualize SAI in Secondary Structure editor window - Go to PROPERTIES menu, click on CHANGE DISPLAY sub-menu and select the 'Visualize SAI' check box.
You can also change the colors used to display SAIs by going to PROPERTIES->CHANGE COLORS AND FONTS menu in the Secondary Editor Window.

## NOTES

### If SAIs are to be visualized in Secondary Structure Editor window, one should select SAI, define CTT and check ENABLE VISUALIZATION check box in Primary structure editor window using VISUALIZE SAI function (under VIEW menu in PRIMARY EDITOR).

### In order to retain the settings of CTT and associated SAIs, one should save the properties by going to PROPERTIES->SAVE PROPERTIES menu in primary editor. Please note that the CTT definitions are stored in the local file (.arb_prop/edit4.arb) and deleting or modifying this file will lose all the information about CTT definitions used for visualization of SAIs for future sessions.
