MacVectorTip: Create custom Codon Usage Tables for ORF analysis and reverse translation

MacVector uses codon usage tables (also called “Codon Bias”) to help you predict protein coding regions in the Analyze | Nucleic Acid Analysis Toolbox functions and also the protein Analyze | Reverse Translation… function. For example, here are the Plus and Minus strand Staden Codon Preference plots aligned under the Plus/Minus ORFs for a Streptomyces […]

MacVectorTip: How to copy a specific short amino acid translation of a sequence

There can be times when you are messing around with open reading frames, inserting residues to change frames to try to get the perfect CDS fusion. The MacVector single sequence Editor will show those (click and hold on the “Display” toolbar button) but if you select and copy, only the DNA sequence (with any overlapping […]

Applescript: batch translation of CDS features

Apple’s AppleScript (along with Javascript for Automation) is an easy to write and easy to understand language that allows you to easily automate tasks in supported applications. Many Apple applications have a AppleScript Dictionary that defines what functions you can automate. MacVector has many such functions in its AppleScript Dictionary. You can auto annotate multiple […]

Optimizing Reverse Translations

The Analyze | Reverse Translation menu option lets you create a DNA sequence from a Protein sequence, reverse translated using a specific Genetic Code (by default, the Universal Genetic Code). The default option creates a DNA sequence with N’s and other ambiguities reflecting the degeneracy of the genetic code. This is great if you want […]

Controlling Automatic ORF Display

MacVector 15.5 automatically scans every DNA sequence window for open reading frames and displays the results in the Map tab. The setting for this are controlled by the MacVector | Preferences | DNA Map pane, along with the automatic Show restriction sites settings. The Minimum Number of Codons setting is fairly obvious. 5’ ends are […]

How to toggle between 1 and 3 letter amino acid codes

MacVector displays amino acid translations in many different result windows. You can drill down to the residue level in the Map tab and see translations of CDS and other translatable features and see translations in the plain text views and the Quicktest Primer interface. The translations can be viewed as either single letter codes or […]

Optimizing the Reverse Translation function

The Analyze | Reverse Translation menu option lets you create a DNA sequence from a Protein sequence, reverse translated using a specific Genetic Code (by default, the Universal Genetic Code). The default option creates a DNA sequence with N’s and other ambiguities reflecting the degeneracy of the genetic code. This is great if you want […]

Displaying CDS features as translations in the Map tab.

Where appropriate, features can be shown as residues when there is sufficient space to show them (for example when zoomed to residue). By default this is enabled for certain features, e.g. CDS features, genes, but it is controlled from the Symbol Editor and can be turned on/off for most features. In the Map tab, double […]
