Nick Loman recommended LAST (not lastz) for mapping oxford nanopore reads. As I have tried, it worked very well at least for small genomes. A few others also seconded. For PacBio, its native mapper blasr is the proven tool, though some complain it is a bit slow. Another option is bwa-mem from github (self advertisement). It is better than the latest release 0.7.10. Bwa-sw is not as good. I reviewed a manuscript where the authors claim that older bwa-mem and bowtie2 don't work well (probably true) and that gem works well, but at my hand gem does not really work at all with their setting. I haven't heard from the authors yet. As to others, blat uses non-overlapping 11bp seeds (by default) and gmap use 20bp (or 24bp) exact seeds. Even if they work, you may need a lot of tuning. According to the email provided by coreruhno, STAR does not work with raw pacbio reads. It only works with CCS reads. Smalt, BBmap and MUMmer are all claimed to work with PacBio reads, but I have not tried myself. Finally, blast, lastz and blastz should also work provided that you use the right settings.

Probably I need to do a brief survey.

Self promotion: PacBio/Oxford Nanopore alignment with bwa-mem:

git clone https://github.com/lh3/bwa.git
cd bwa; make
bwa index ref.fa
bwa mem -x pacbio ref.fa pacbio.fq > aln.sam
bwa mem -x ont2d ref.fa ont-2D.fq > aln.sam

I really like STAR as an aligner, and recommend it if you have a high-memory pc or cluster. It can be configured for use with long reads. See here.

Just look this up yesterday, go take a look at bwa's long read Version: bwa-sw
