this is not a #chant #fragment but it not #chant in a pretty interesting way! also Tudor music is fun so here is a thread about a "Fayrfax" "O lux" (scare quotes on both counts) 1/
so this is a lil piece of instrumental polyphony, written (somewhat unusually) in score notation. the paper has some 6-line staffs, so it probably was meant for a few vocal lines and some lute tabs, but our guy is using the six-line staff for the top bc it has the most wiggles.2/
piece also has some little rhythmic games where you count 4 against 3. very popular hobby in sixteenth-century Britain: seeing if you can throw off your fellow musicians. 3/
(1/7) A quality control tool for raw #sequence data. Using #FastQC you may check:
🚀 Per base sequence #quality (do you see a drop in sequencing quality near the read end?). This view shows an overview of the range of quality across all bases at each position in the FASTQ file.
🚀 Per base sequence #quality (do you see a drop in sequencing quality near the read end?). This view shows an overview of the range of quality across all bases at each position in the FASTQ file.
(2/7) Per sequence quality scores (how many reads are the best?) The per sequence quality score report shows whether a subset of sequences has universally low-quality values.
(3/7) Per base sequence content (the proportion of each base position in a file for which each of the four normal #DNA bases has been called). Ideally, in a random library, we would see four parallel lines representing the relative base composition.
