Bowtie 2 seems to be working fine (tested command 'bowtie2 --version' [2.5.4]) Output format is BAM (default) Alignments will be written out in BAM format. Samtools found here: '/srlab/programs/samtools-1.20/samtools' Reference genome folder provided is ../../data/genome/ (absolute path is '/mmfs1/gscratch/scrubbed/sr320/github/ceasmallr/data/genome/)' FastQ format assumed (by default) Processing sequences up to read no. 10000 from the input file Attention: early reports suggested that high values of -p to have diminishing returns. Please test different values using a small subset of data for your hardware setting. 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 '/mmfs1/gscratch/scrubbed/sr320/github/ceasmallr/output/04-bismark-align'): ../../data/CF08-CM03-Zygote_R1_001.fastp-trim.20220827.fq.gz ../../data/CF08-CM03-Zygote_R2_001.fastp-trim.20220827.fq.gz Library was specified to be not strand-specific (non-directional), therefore alignments to all four possible bisulfite strands (OT, CTOT, OB and CTOB) will be reported Output will be written into the directory: /mmfs1/gscratch/scrubbed/sr320/github/ceasmallr/output/04-bismark-align/ Setting parallelization to single-threaded (default)
