The Goto Menu

The items in this menu allow the user to navigate around the sequence and features.

Goto ...

Open a new navigation window. This window allows the user to do three things:

  1. Scroll all the views so that a particular base is in the centre of the display. To use this function, type a base position into the box to the right of the "Goto Base:" label then press return or press the goto button at the bottom of the window. The requested base will be selected and then the overview display and the DNA display will scroll so that the base is as near as possible to the middle of the main window.

  2. Find the next feature that has a qualifier containing a particular string. To use this function, type a string into the box to the right of the "Goto Feature With This Text:" label and then press return or press the goto button. If the "Start search at beginning" option is set or there are no selected features, Artemis will select the first feature with the given string in any of it's qualifier values. If the "Start search at selection" option is set, the search will start at the next feature after the selected feature (if any). Pressing return or the goto button again will move to the next matching feature.

  3. Find the next occurrence of a particular base pattern in the sequence. To use this function, type a base pattern into the box to the right of the "Goto Base Pattern:" label and then press return or press the goto button. If the "Start search at beginning" option is set or there are no selected bases, Artemis will select the first contiguous group of bases on either strand that match the given base pattern. If the "Start search at selection" option is set, the search will start just after the selected bases (if any). Pressing return or the goto button again will move to the next matching bases.

    Any IUB base code can be used in the pattern, so for example searching for aanntt will match any six bases that start with "aa" and ends with "tt".

Goto Start of Selection

Scroll all the views so that the first base of the selection is as close to the centre as possible. If the a range of bases is selected the views will move to the first base of the range. If one or more features are selected, then the first base of the first selected feature will be centred. Otherwise, if one or more segments (see the section called Feature Segments in Chapter 2) is selected then the first base of the first selected segment will be centred.

Goto End of Selection

This does the same as "Goto Start of Selection", but uses the last base of the selected range or the last base of the last selected feature or segment.

Goto Feature Start

Scroll the views to the start of the first selected feature.

Goto Feature End

Scroll the views to the end of the first selected feature.

Goto Start of Sequence

Scroll the views so that the start of the sequence is visible.

Goto End of Sequence

Scroll the views so that the end of the sequence is visible.

Goto Feature Base Position

Ask the user for a base position within the first selected feature, then scroll the views so that that base position is centred.

Goto Feature Amino Acid

Ask the user for an amino acids position within the first selected feature, then scroll the views so that that position is centred.
