BWA is the natural replacement, but it does not use base qualities. That should not stop you from using it. You'll see it preforms very well. It comes from the author of MAQ.
You can also try bfast.

Thank you for the response!
I have heard of Novoalign and its reputation but I was hoping that there was a newer, open source algorithm available to replace MAQ, mostly because I want to use it and its a pain to implement it with large data volumes.

What papers are you refering too? Did they recalibrate the quality scores?
That could be a good reason since it has proven to increase accuracy. Check the
latest alignment review from Homer and Li (Heng and Nils). In Fig 3 they show
how both novoalign (not opensource) and MAQ behave with and without using
base quality.

Bowtie also uses base quality. Novoalign is not opensource but seems to be
the most accurate aligner out there. So you may want to give it a try. You
can try it out for free.

MAQ and quality scores during alignment
Hi,
I have seen some recent papers using MAQ and assume it is because it includes quality information?
Do you know of any better open source software that does this? I initially thought that quality scores weren't so useful, do they generally improve alignments or are they only useful in specific circumstances?
Thanks in advance!Tags: None

The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...-

Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...-
