    You can use the Analyze | Open Reading Frames function to very quickly find ORFs on a sequence. Did you know that you can very quickly turn those results into permanent CDS features on your sequence? After running the Open Reading Frames analysis, simply drag and drop the ORF objects you are interested in from…

  • Importing sequences/features from websites such as ENSEMBL or UCSC’s Genome Browser

    Many Genome Browsers/databases allow you to browse and view genomes, or a specific gene/region, with a high degree of detail. For example ENSEMBL and the UCSC Genome Browser. However, many times you want to work with that data on your own Mac. As usual the easiest way to exchange sequence data is using the Genbank…

    The Map tab is a powerful way to visualize and interact with your sequences. You can design primers, ligate and digest fragments from the Cloning Clipboard, visualise translated CDS regions and much more. The Map tab of a Results window is just as flexible as the Map tab of the main sequence window. You can…

    You can very quickly annotate a region of interest in your sequence in the Editor tab. For example showing introns in lower case or highlighting CDS features with a colored background. To enter sequences as mixed case. Enable Edit | Transformations | Enable Mixed Case Entry Type your sequence using SHIFT or CAPS LOCK To…

  • Displaying features in the Editor tab

    The Map tab shows a richly detailed graphical representation of your sequence. However, sometimes you just need a overview of annotation along with sequence. MacVector makes it easy to display features directly on the sequence in the Editor tab. Only a subset of a sequence’s features are displayed due to limited room. You can choose…

  • Editing the appearance of your sequence maps

    Although we think that the default appearance of sequence maps in MacVector is very pretty, sometimes the defaults are not to everybody’s taste! If you think this way, then changing how maps look is very easy. As usual with MacVector, there are many ways to quickly edit the appearance of a feature or multiple features.…

  • How to increase the number of graphics levels to stop features overlapping.

    MacVector tries to optimize the Map graphics layout using a trade-off between performance and minimizing unnecessary white space. Sometimes the default settings we have chosen are not ideal, particularly if you are looking at the Map tab of an Align To Reference window where you have a large number of reads overlapping the same region.…

  • 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…

  • Using BLAST to automatically annotate a sequence

    You can use the Database->Auto-Annotate Sequence function to quickly annotate a bare sequence using existing annotated sequences on your file system. However, this only works if your collection of sequences contains features representing all parts of the bare sequence. Luckily, if you have an unannotated region after running Auto-Annotate, you can use MacVector’s built-in BLAST…

  • How to import annotated GenBank sequences via copy and paste

    While MacVector does have a built-in Entrez browser (Database > Internet Entrez Search) you can easily import GenBank formatted text into MacVector via a simple copy and paste approach. Many sequence-oriented web sites have the option of viewing sequences in GenBank format. This format always starts with the text LOCUS and finishes with two forward…
