Blixem is an interactive browser of sequence alignments that have been stacked up in a "master-slave" multiple alignment; it is not a 'true' multiple alignment but a 'one-to-many' alignment.

Dotter is a graphical dot-matrix program for detailed comparison of two sequences. Belvu is a multiple sequence alignment viewer and phylogenetic tool with an extensive set of user-configurable modes to color residues. Our primary supported platform is Ubuntu SeqTools is well tested and in daily use on this architecture. It is also tested frequently on Mac OS X. It should also work on several other platforms, as listed below, but is less thoroughly supported.

As well as being used independently, Blixem, Dotter and Belvu can also be called from other tools as part of a software pipeline. A common workflow is to call Blixem from the ZMap genome browser to analyse a set of alignments in more detail, and to call Dotter from within Blixem to give a graphical representation of a particular alignment. Belvu has an extensive set of command-line arguments for specifying processing and output parameters, making it possible to perform complete processes in a single command-line call.

See our team page for more information. Version 4 of the programs involved an extensive re-write to take advantage of modern GUI toolkits and to separate them from AceDB to form this independent SeqTools package.

They can be used independently or with any other tool that outputs data in a suitable format - the current preferred file formats are FASTA and GFF v3 for Blixem and Dotter; a variety of file formats are supported by Belvu.

Please download the latest version from the FTP site. Experimental code; not guaranteed to be stable or even to compile. Should only be used if you require the very latest changes. To install in a different location, or for help with dependencies, see the tips section.

SeqTools cannot currently run natively on Windows. However, it can be installed and run in a virtual machine VM using VirtualBox. It should also be possible to install SeqTools using Cygwin which provides a Linux-like environment on Windows. The VM uses more disk space and memory, but is likely to be more robust because it can emulate our primary supported architecture.

You should then be able to install SeqTools by following the standard Linux instructions above.In bioinformatics a dot plot is a graphical method that allows the comparison of two biological sequences and identify regions of close similarity between them.

YASS :: genomic similarity search tool

A dot plot is a simple, yet intuitive way of comparing two sequences, either DNA or protein, and is probably the oldest way of comparing two sequences [Maizel and Lenk, ]. Principle Dot plot are two dimensional graphs, showing a comarision of two sequences. The principle used to generate the dot plot is: The top X and the left y axes of a rectangular array are used to represent the two sequences to be compared. A dot is plotted at every co-ordinate where there is similarity between the bases.

Dot plot algorithm: As an initial example for dot plots one can imagine the same sequence written onto two strips of chequered paper. Every symbol of the sequence is written consecutively into one chequer, with its index number next to it. By overlaying a frame containing a window that allows viewing exactly one symbol of each strip at a time symbols are compared in pairs. Whenever symbols in the observing windows match, a bright dot is placed in a grid at the respective indices.

The resulting rectangular graphical representation is a dot plot. It thus represents all possible comparisons of characters in either sequences and is colour-coded with two colours indicating a match or mismatch between any two characters.

The resulting rectangular graphical representation is a dot-plot. Problem: Plot becomes too noisy when we compare large and similar sequences. For DNA sequences the background noise will be even more dominant as a match between only four nucleotide is very likely to happen. How do we choose a window size?

Window size changes with goal of analysis — size of average exon — size of average protein structural element — size of gene promoter — size of enzyme active site.

How do we choose a threshold value? How dot plot created? Dot plots compare two sequences by organizing one sequence on the x-axis, and another on the y-axis, of a plot. When the residues of both sequences match at the same location on the plot, a dot is drawn at the corresponding position. Note, that the sequences can be written backwards or forwards, however the sequences on both axes must be written in the same direction. Also note, that the direction of the sequences on the axes will determine the direction of the line on the dot plot.

Once the dots have been plotted, they will combine to form lines. The closeness of the sequences in similarity will determine how close the diagonal line is to what a graph showing a curve demonstrating a direct relationship is. This relationship is affected by certain sequence features such as frame shifts, direct repeats, and inverted repeats.

Frame shifts include insertions, deletions, and mutations. The presence of one of these features, or the presence of multiple features, will cause for multiple lines to be plotted in a various possibility of configurations, depending on the features present in the sequences. Low-complexity regions are regions in the sequence with only a few amino acids, which in turn, causes redundancy within that small or limited region.

These regions are typically found around the diagonal, and may or may not have a square in the middle of the dot plot. What for dot plot is used? A dot plot is a 2 dimensional matrix where each axis of the plot represents one sequence.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

AutoManager only supports four printer models for dot matrix printing. After selecting your form from the forms list, you will see the margins tool.

Keep the margins set at 0, 0 the first time you print the form. When your form is done printing you can determine how far off your text is from where it is supposed to be. It is best to use a ruler at this point.

Measure, in inches, how far and what direction your text is off. In this example, the text is printing approximately a quarter of an inch too high. When you go to print that form again you can input your margins. We give you a scale above where you input your margins telling you points are equal to. Putting a larger number into your Top Margin box will move your text down the page next time you print whereas putting a negative number will move it up the page.

Likewise, putting a larger number into your Left Margin box will move your text to the right next time you print whereas putting a negative number will move it to the left. Please note that a negative margin will only move the text over to a certain point before the text starts to get cut off.

From the example above, the print job was approximately a quarter of an inch too high. Using the margins in the example above, this is the result. Knowledge Base. Aligning Dot Matrix Forms.

Note: Use coarse adjustments only if you are using checks, invoices, or forms purchased from Intuit. Other continuous-feed forms can't be adjusted using this method. If your coarse adjustments are successful, you will not need to make fine adjustments. Before doing any adjustments, make sure your continuous-feed printer is turned on and connected to your computer, and that the forms you want to print are in the printer's paper feed.
