Quickly checking a small sequencing project
For analysing large sequencing datasets, whether de novo or mapping reads against a reference you need Assembler. However, many times you do not need a powerful tool but just a quick way to check some sequencing data. For example for checking small sequencing projects, such as a site directed mutagenesis, looking for SNPs in a…

101 things you (maybe) didn’t know about MacVector: #41 – Extracting raw data from chromatogram files
Have you ever wanted to know exactly what the total signal value is for individual peaks in a chromatogram file? Perhaps you are looking for mixtures of residues at a particular location and want to get some idea of the relative proportions? You can open .ab1 and .scf chromatogram files directly in MacVector and view…

101 things you (maybe) didn’t know about MacVector: #40 – Removing gaps from a DNA or protein sequence
There are often times when you end up with a sequence containing gaps, especially if you make extensive use of the Align To Reference, Contig Assembly or Multiple Sequence Alignment interfaces to generate consensus sequences. You can select and copy the consensus sequence, or even individual aligned reads, from the Align To Reference and Contig…

MacVector 13.5 is out
MacVector 13.5 was released last week. MacVector 13.5 is the best release yet. It’s had a redesign and rewrite of existing tools to make comparing large sequences faster and to improve handling of NGS data. Additionally the new interface, introduced in MacVector 13.0, has had many “tweaks” in response to user feedback. Plus a continued…

Accessing BAM files from an Assembly Project file
All assemblies are stored using the BAM file format. This is a binary file that stores each read and where and which consensus/contig/reference it is mapped against. It is a compressed version of the pure text SAM format. For some post assembly tasks it is necessary to do further processing on the BAM file. To…

de novo assembly with Velvet
Velvet is a short read aligner that works very well on a wide variety of reads. Velvet excels at de novo assembly of sequencing reads from second and newer generation sequencers. In our latest release, MacVector 13, we’ve added Velvet to Assembler. This joins the existing tools, Phrap for Sanger sequencing reads and Bowtie for…

Public beta of MacVector 13
There’s a public beta of our imminent release MacVector 13 ready for downloading and testing on our website. You just need an active license for MacVector 12.7 to run this. Watch out for the new easier way of installation (no installer, just drag to your Applications folder!). As well as a redesign of the interface…

101 things you (maybe) didn’t know about MacVector: #18 – Aligning Chromatogram (ABI) Sequences
I blogged about this a few years ago, but its something that still comes up on a regular basis. The blog link discusses the 6 main alignment algorithms in MacVector and how to decide which is the most appropriate for accomplishing different tasks. One common request we get is “I want to see my chromatograms/traces…
