*** Bismark methylation extractor version v0.19.0 *** Setting option '--no_overlap' since this is (normally) the right thing to do for paired-end data Summarising Bismark methylation extractor parameters: =============================================================== Bismark paired-end SAM format specified (default) Number of cores to be used: 8 Output will be written to the current directory ('/Users/yaamini/Documents/project-virginica-oa/analyses/2018-05-04-Bismark-Full-Samples') Summarising bedGraph parameters: =============================================================== Generating additional output in bedGraph and coverage format bedGraph format: coverage format: Using a cutoff of 1 read(s) to report cytosine positions Reporting and sorting cytosine methylation information in CpG context only (default) The bedGraph UNIX sort command will use the following memory setting: '2G'. Temporary directory used for sorting is the output directory Checking file >>zr2096_10_s1_R1_val_1_bismark_bt2_pe.deduplicated.bam<< for signs of file truncation... The IDs of Read 1 (HWI-C00124:321:CC781ANXX:2:1202:8775:19934_1:N:0:GATCAG) and Read 2 (HWI-C00124:321:CC781ANXX:2:2306:3960:72707_1:N:0:GATCAG) are not the same. This might be the result of sorting the paired-end SAM/BAM files by chromosomal position which is not compatible with correct methylation extraction. Please use an unsorted file instead or sort the file using 'samtools sort -n' (by read name). This may also occur using samtools merge as it does not guarantee the read order. To properly merge files please use 'samtools merge -n' or 'samtools cat'.
