Bowtie 2 seems to be working fine (tested command '/home/shared/bowtie2-2.4.4-linux-x86_64/bowtie2 --version' [2.4.4]) Output format is BAM (default) Alignments will be written out in BAM format. Samtools found here: '/usr/bin/samtools' Reference genome folder provided is ../data/ (absolute path is '/home/shared/16TB_HDD_01/sr320/github/project-mytilus-methylation/data/)' FastQ format assumed (by default) Processing sequences up to read no. 10000 from the input file Attention: using more than 4 cores per alignment thread has been reported to have diminishing returns. If possible try to limit -p to a value of 4 Each Bowtie 2 instance is going to be run with 8 threads. Please monitor performance closely and tune down if necessary! Input files to be analysed (in current folder '/home/shared/16TB_HDD_01/sr320/github/project-mytilus-methylation/code'): ../data/93M_R1.fastp-trim.fq.gz ../data/93M_R2.fastp-trim.fq.gz Library is assumed to be strand-specific (directional), alignments to strands complementary to the original top or bottom strands will be ignored (i.e. not performed!)
