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 […]

Calculating the melting temperature of PCR primers

Calculating an accurate melting temperature of your oligos, your template and of the predicted product is important to set the cycling parameters of your PCR machine. The Tm calculations in MacVector were updated in MacVector 12.6 to use a more modern algorithm. MacVector has always used thermodynamic “nearest neighbor” calculations, but there were two changes […]
