Gonad Methylation Analysis Part 5
When the stars (and sequences) align
I successfully completed my genome preparation in Bismark yesterday, so I started on my sequence alignment. Based on the Bismark manual and Steven’s lab notebook post, I used the following parameters in my Jupyter notebook:
- Path to Bismark
- -u 10,000: Allows me to subset the first 10,000 reads from each input file
- –nondirectional: See this issue
- –score_min L,0,-1.2: This was a parameter Steven used to allow for mismatches in alignment
- –genome + path to the folder with the .fa genome and bisulfite genome directories Bismark prepared earlier
- Path to sequence files for alignment
The Bismark run was completed for each file, but I did end up with a gunzip
error for each of my files:
I’m not entirely sure what this means, so I opened a new issue. Once I fix this gunzip
problem, I can move on to the methylation extraction and start to analyze all of the .bam files this alignment step produced!
