Viewing external database entries for features in a sequence.

Sequences, or regions of sequences, can be linked to external databases. For example an entire sequence entry or for when annotation tools are used to annotate proteins with domain or motif information (for example InterProScan). Very useful for when you want to view more detailed or updated information. Within the Genbank specification, which MacVector extensively uses, […]

Use the Replica Button For Synchronized Views

Most primary MacVector windows (Nucleic Acid Sequence, Protein Sequence, Multiple Sequence Alignment, Align To Reference, Contig Assembly etc.) have a Replica toolbar button. If you click that button, a second window will open, potentially set to a different tab. The key to this functionality is that the two windows are linked – any selections you […]

How to Identify Bacterial Promoters Using MacVector

MacVector’s Subsequence tool is a very flexible search function that can be used for a variety of tasks. MacVector itself has a built-in variant of the function for maintaining and search primer databases (Analyze | Primer Database Search…). Each entry in the file MacVector uses as a source of subsequence data can have up to […]

Import Multi-Sequence Genbank Files into an Assembly Project for easy access to Features

There are many genomes in the Genbank database that cannot be downloaded as single annotated sequences. These might be large multi-chromosome eukaryotic genomes, but, increasingly, partially sequenced bacterial chromosomes where the major contigs have been annotated using the NCBI annotation pipeline. Typically, when you encounter these, there are options to download annotated versions of these […]

Searching and downloading sequences from Entrez

MacVector has integrated connectivity to the NCBI BLAST and Entrez databases. You can directly search Entrez for DNA or Protein sequences based on features, authors, keywords etc and directly download them into MacVector, complete with all features and annotations. Tweet

Using MacVector’s Auto Annotate tool to annotate blank sequences.

  Have you ever been sent a plain unannotated sequence, or downloaded a sequence from Entrez and been disappointed as it doesn’t have the carefully curated graphical appearance of your favorite genes? Auto annotation solves both of these common problems. The basic idea is that you can scan the sequence against a folder containing a […]

Annotating primers to your sequence with MacVector

Designing a pair of primers to amplify a single feature is pretty quick with MacVector. Once you have designed a pair of primers with MacVector, you can quickly annotate both the primers and product to your sequence template. The annotation contains a timestamp and the primer’s characteristics. It also contains the full sequence of the primer, […]

Downloading hits from the MacVector BLAST Map results tab

MacVector’s BLAST Map results tab (added in MacVector 15.5) is a unique interface for examining the annotations around hits to a query sequence. Each pane in the display represents a High Scoring Segment Pair, as seen in the BLAST Aligned Sequence tab. At the lower left corner of each pane is a Download button – […]

Turning on/off the SCAN FOR missing Features and ORFs

If you’re running MacVector 15.5 or later then you will have noticed extra features annotated to your sequences. These are from the Scan for ORFs tool (added in MacVector 15.5) and the Scan For Missing Features (added in MacVector 16) tools that automatically scan every DNA sequence window for open reading frames, missing annotations and […]
