Can we take advantage of nanopore sequencing systematic errors to predict secondary structure motifs?

One of the methods of single-molecule sequencing, Nanopore sequencing, is based on traversal of DNA strand through a nanopore. Nucleotide is determined by measurement of ion current (when nucleotide ...

Is the default kmer 25 value in Trinity still ok for assembly of 150bp reads from Illumina HiSeq 2500?

I will soon be receiving Illumina HiSeq 2500 data (150bp PE stranded reads). In the past we have been using Trinity as our assembler of choice, but it uses a default kmer value of 25. I believe this ...
