101 things you (maybe) didn’t know about MacVector: #10 – Displaying Amino Acids As Triple Letter Codes In Translations

Following on from my last post about turning on translations in the sequence Editor, I thought I should point out how to display amino acid translations using the 3-letter code rather than the default single-letter code. I don’t know about you, but I have a hard time remembering that “W” is the single-letter IUPAC code for tryptophan, whereas “Trp” is pretty obvious. To get to the setting, choose MacVector | Preferences to open up the preferences dialog. Switch to the Text View tab and click on the three button in the Characters group;

TripleLetterAACodeButton.png

When you close the Preferences window, or click Apply, any open windows will update to show the new settings. So, the sequence Editor will show the three letter codes;

…and any annotated text windows will also show the 3 letter codes;

101 things you (maybe) didn’t know about MacVector: #9 – Showing Translations In The DNA Sequence Editor

If you have used MacVector for many years, you’ll remember the days when the single sequence editor was THE main way you interacted with MacVector. When MacVector 10 was introduced back in 2007, the Editor became just one tab in the single sequence window along with Map, Features and Annotations tabs, all of which at one time were separate windows. What you may not realize is that there have been a number of improvements made to the Editor over the intervening years, one of which is the ability to display amino acid translations above and below the DNA sequence;

pBR322TetTranslation.png

There are a number of different options for displaying the translation – all are accessed via the Strands toolbar button. If you click on this and hold the mouse button down, a popup menu will appear and you can toggle each menu item;

StrandsButtonAnimated.gif

The menu options are;

Show CDS Translations – this shows the translations for any CDS features that are present in the sequence. “CDS” features are the standard GenBank features describing the start and stop location of translated open reading frames on an annotated sequence.

Show Complementary Strand – this is the classic MacVector option to display the complementary nucleic acid strand.

Show Plus Strand Translations – this shows the +1, +2 and +3 strand translations above the sequence.

Show Minus Strand Translations – this shows the -1, -2 and -3 strand translations below the sequence.

All of the translations are dynamic, i.e. they update in real time as you type. The translations key off the currently selected genetic code, usually the Universal code, but yo can change it using the Options | Modify Genetic Codes menu item.

101 things you (maybe) didn’t know about MacVector: #8 – Tutorials

Some of the most common support calls we get are from users who are not sure how to use a particular feature in MacVector and would appreciate having someone walk through the steps with them. In many of these cases, it turns out that we have published tutorials that have exactly the information they are looking for, but it wasn’t obvious where to find them.

When you install MacVector, it usually gets installed in a folder in the system /Applications/ folder e.g. MacVector 12.6 can be found in the /Applications/MacVector 12.6/ folder. Inside that folder, you will find a folder called /Documentation/. This has electronic versions of the User Guide (MacVector User Guide.pdf) and the Getting Started Guide (GettingStartedGuide.pdf) along with a number of technical “Read Me” files for many of the 3rd party algorithms, plus the following Tutorials;

Align To Reference – Sequence Confirmation Tutorial This shows how you can align one or more sequences (including chromatogram files and next generation sequencing FastQ files) against a reference sequence to confirm the sequence of the reference, look for SNPs in the aligned sequences or screen for successful mutagenesis clones.

Auto Annotation Tutorial This describes the functionality in MacVector that lets you automatically annotate a sequence based on a collection of existing sequences on your hard drive.

Click Cloning Tutorial A tutorial showing how you can create new constructs by simply clicking on restriction enzyme sites, copying fragments and pasting into target vectors.

Gateway+TOPO Tutorial A variant of click cloning using the popular Gateway and TOPO cloning strategies from Invitrogen.

Primer Design Tutorial Check this out to learn about how to use the new interactive Quicktest Primer interface to design primers and find matching primer pairs using Primer3.

Contig Assembly Tutorial A basic tutorial on how to use the add-on Assembler module to assemble sequences from ABI files using the popular phred/phrap/cross_match algorithms from the University of Washington.

NGS Reference Alignment Tutorial How to use the Assembler module to align millions of reads from next generation sequencing runs to genomes using the Bowtie algorithm.

You can also download the tutorials from the Downloads page of our web site.

All of the tutorials use sample sequence files that are found in the /Applications/MacVector 12.6/Tutorial Files/ folder. This folder does NOT contain the actual tutorials, just the sample sequence files – perhaps we need to change that as it does confuse many people.

If you’d like to see tutorials on other subjects, please comment on this blog or send an e-mail to support@macvector.com letting us know.

101 things you (maybe) didn’t know about MacVector: #7 – Copying the graphical appearance of a feature

Following on from the graphics tips of the last few posts, here’s one that can save you a lot of time if you are the sort that likes to keep the appearance of your features consistent between sequences (like me). Suppose you have downloaded a sequence from Entrez, or been sent a sequence in GenBank format by a collaborator, and you want to clean it up and make the graphics look nice. Here’s a boring plasmid with the default graphical appearance of a set of gene features;

BoringPlasmid.png

The first step is to select the feature you want to change – in the image above the AraC gene has been selected, but you can select multiple features so you can change several at one time. Now click on the Copy Feature Appearance button on the Graphics Palette;

CloneAppearanceButton.png

The pointer will change to an eye dropper. Position the pointer over the feature whose appearance you want to copy and click the left mouse button. The feature can be in the same window, or, as in the example below, it can be in a different window. There is no need to make that window the active frontmost window – just directly click on the feature;

CloneAppearanceWithDropper.png

The selected feature in the original sequence will then update to match the appearance of the feature you clicked on. Every aspect of the source feature’s graphical appearance is copied – the shape, colors, font, position on the map and even any meta tags associated with the label;

101 things you (maybe) didn’t know about MacVector: #6 – Getting Graphics Out of MacVector

MacVector’s Map graphics can provide highly detailed views of individual sequences in linear or circular format, or of the results of many analyses. You can print these to a printer with no loss of detail, even if blown up to many magnifications. However, it is often more useful to insert these graphics into other applications such as Microsoft PowerPoint or Adobe Illustrator, or perhaps to save in a suitable format for publishing on a website or a blog.

By far the simplest way to accomplish this is to make sure your graphic is sized appropriately within the MacVector window, then simply choose Edit | Copy. There is no need to make any selection in the window – Edit | Copy will copy the entire graphic to the pasteboard, including any areas that are not currently visible. The data is copied in “PDF” format. This is the popular Portable Document Format more typically associated with document files, but is also used internally by the Mac OS X pasteboard to transfer high quality vector graphics between applications. Once copied from MacVector, you can then directly paste the high quality vector graphics data into most modern graphical applications, including TextEdit, Preview, MS Word, MS PowerPoint, Illustrator, InDesign, Photoshop, Pages, Keynote and many others.

If you would prefer to have the graphical data saved to a file in a particular format (e.g. jpg, png, tif etc) the simplest way is to perform Edit | Copy as described above, then switch to Apple’s Preview.app. This is installed on every Macintosh and can be found in the /Applications/ folder. From Preview, choose File | New From Clipboard and the copied graphics will appear in a new window. Finally, choose File | Save As… and you can choose from most of the common graphics file formats;

101 things you (maybe) didn’t know about MacVector: #5 – Printing Graphics Onto A Single Page

The Map tab of MacVector’s single sequence editor displays highly detailed graphics showing sequence in circular or linear format. It is highly customizable and the graphics can be printed or copied to other applications using Apple’s internal PDF vector graphics format, resulting in images that can be scaled to any size with no loss of resolution. However, Maps can often become very busy, with many features and restriction enzyme sites jostling for position. When this happens, it can be tricky to ensure that the Map will print on a single page. Here are a few tips to help make sure that happens.

a) There is a Print To Page button in the floating Graphics Palette;

PrintToPageButton.png

Click on this and MacVector attempts to fit the graphics onto a single printed page, taking the currently selected page size and magnification into account. Sometimes, especially with crowded restriction maps, this may not always quite get the scaling exactly right.

b) To get a preview of the actual printed page in relation to where the graphics will lie, click on the Page Preview button at the bottom left of the window. This turns on dotted lines that will show you exactly where the pages will break when printed.

PagePreviewButton.png

If the page breaks don’t occur where you would like them, try changing the Radius in the Graphics Palette or use File | Page Setup and reduce the Scaling until the preview indicates the graphic will fit on a single page.

101 things you (maybe) didn’t know about MacVector: #3 – The Importance of Topology

MacVector understands the difference between circular DNA molecules and linear DNA molecules. Not just from the standpoint of how the molecule is displayed on the screen, but also in regard to how the analysis algorithms handle the junction at the ends of the circle. The Topology button controls the underlying linear versus circular state of the molecule. It is always shown on the toolbar of DNA/RNA sequence windows and can have two states;

TopologyButton.png

Lets look at an example to see how this works. pBR322 is a classic vector that has its circular origin defined as the center of the EcoRI site that is traditionally placed at the 12 o’clock position on the map;

pBR322circular.png

You can use MacVector’s Graphics Palette to show the molecule in linear form. However, note that the EcoRI site is still displayed because although we are viewing the molecule as if it is linear, the Topology button is still set to circular, so the EcoRI site is still present.

pBR322linear.png

But if we click the Topology button, this changes the sequence from circular to linear so the sequence around the original EcoRI site goes from …xxxGAATTCyyy… to 5′-TTCyyy……xxxGAA-3′. The two halves of the site are now at opposite ends of a linear molecule, so no EcoRI site is present;

pBR322reallylinear.png

MacVector enforces this topology status when considering if a molecule can be displayed in circular form. It ONLY allows circular molecules to be displayed as a circle in the Map tab so that you don’t think you are working with a circular molecule when “under the hood” you are not. The solution is simple though – just click the Topology button!

101 things you (maybe) didn’t know about MacVector: #2 – Option-click to open the Default Symbol editor

If you download sequences from BLAST or Entrez, or import GenBank or EMBL files with lots of features, you may wish that the features (genes, CDS, promoters etc) showed up differently in the Map tab, or maybe your favorite features don’t show up at all unless you turn them on using the Graphics Palette. Its easy to change the default appearance of features using the Default Symbols editor. If you have just opened MacVector, and there are no sequence windows open, you can access the Default Symbols editor from the Options menu;

DefaultSymbols.png

However, if you have a sequence file open, then the menu is set to edit the symbols for just that file;

pBR322Symbols.png

To access the Default Symbol editor when a sequence window is open, hold down the option key and the menu item will change once again to Default Symbols. If you select that, the Default Symbol editor will be displayed and you can edit the appearance and initial visibility of each type of feature;
