Weekly Tip: Use Hash Value = 12 for speedy genome comparisons with Create Dot Plot

MacVector’s Analyze | Create Dot Plot function can be used to compare entire genomes very quickly to get both an overall view of similarity (large inversions and duplications) while providing the ability to “drill down” to the residue level to see individual SNPs. One of the keys to ensuring the calculations complete in a reasonable […]

MacVector’s Primer Database – Importing primers from Excel

Many molecular biologists keep lists of their primer sequences in Excel or some other spreadsheet tool. Previously MacVector had a separate utility that allows you to import primers kept in spreadsheet format into a Primer Database for direct use within MacVector. With the release of MacVector 18.2 we have integrated this functionality within MacVector. Rather […]

MacVectorTip: Using the Align to Reference Shading and Trimming toolbar buttons

MacVector’s Align to Reference Editor and the Contig Editor in Assembly Projects have two useful functions for visualizing assemblies. The Shading button turns on background coloring of the residues in the upper pane, based on quality values (these can be from Sanger reads or from NGS reads). The scale ranges from a dark red for […]

MacVector Tip: a complex subsequence pattern example.

MacVector’s Subsequence tools allows you to search for motifs in both protein and DNA sequences. As well as a library of existing subsequence files, such as promotors and transcription factor binding sites, you can keep a library of your own subsequence matches. Subsequences libraries are multiple patterns kept in a single file. A search will […]

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 […]

MacVectorTip: Context-sensitive Menus in MacVector

Although Apple are well known (notorious?) for always providing mice with only a single obvious button, in reality the Mac interface from early versions of MacOS all the way to macOS Big Sur, plus many Mac apps, have always used right click menus (or more accurately “context sensitive menus”) to provide extra functionality. MacVector is […]
