The Create Menu

This menu contains functions for creating new features (see the section called EMBL/Genbank Features in Chapter 1) or entries (see the section called The "Entry" in Chapter 1).

New Feature

Create a new feature in the default entry with a key of "misc_feature" (see the section called EMBL/Genbank Feature Keys in Chapter 1), a location of that spans the whole sequence and which has no qualifiers (see the section called EMBL/Genbank Feature Qualifiers in Chapter 1).

Feature From Base Range

Create a new feature in the default entry with a key of "misc_feature", no qualifiers and a location that exactly matches the selected range of bases. If no bases are selected an error will be reported. [shortcut key: C]

Intergenic Features

Create new features between CDS features in the default entry all with the "misc_feature" key.

Features From Non-matching Regions

Create features in ACT spanning all the regions where a match is not to be found.

New Entry

Create a new entry with no name and no features. The new entry will become the default entry (see the section called The Default Entry in Chapter 1).

Mark Open Reading Frames ...

Create a feature for each "large" open reading frame in the sequence. The default minimum size of a "large" open reading frame can be changed by changing the minimum_orf_size option (see the section called minimum_orf_size in Chapter 5). If a codon usage file (see the section called Add Usage Plots ...) has been read each new ORF will have a codon usage score added as a /score qualifier. The new features can then be filtered from the display (see "Set Score Cutoffs ..." in the section called The Pop-up Menu).

Mark Empty ORFs ...

Create a feature for each open reading frame that doesn't already contain a feature.

Mark Open Reading Frames In Range ...

Create a feature for each "large" open reading frame in a range of bases. A range must be selected before using this command.

Mark From Pattern ...

Open a text requester to ask the user for a base pattern, then create a feature for each group of bases that matches that pattern. A new entry will be created to hold the features with the name "matches: <pattern>", where <pattern> is the pattern that was entered be the user. Any IUB base code can be used in the pattern, so for example, aanntt will match any six bases that start with "aa" and ends with "tt".

Table 3-1. IUB Base Codes

R = A or GS = G or CB = C, G or T
Y = C or TW = A or TD = A, G or T
K = G or TN = A, C, G or TH = A, C or T
M = A or C V = A, C or G

Mark Ambiguities

Create a new feature for each block of ambiguous bases. The new features will have a key of misc_feature and will created in a new entry called "ambiguous bases".
