Reads were trimmed for quality when the average Phred sequence quality over a 5 bp window dropped below 20, trimmed for adapter sequence contamination, and discarded if the final length was shorter than 35 b.
Prior to assembly raw sequencing reads were filtered and trimmed with Trimmomatic v0.32 [ 93] using the following steps: (1) leading and trailing bases of low quality or N bases were removed, (2) the 3′ end was cut and removed if the quality score of a 4 bp wide sliding window dropped below 15, and (3) remaining reads less than 36 bp and singletons were removed.
Astonishingly, the robber fell as he jumped from a hotel window dropping his loot, but was still able to gather up the most expensive pieces and escape.
They would fire a few shots from a window, drop their weapons, run away as though they were civilians, then go to another location where they had hidden other weapons and fire those.
The season finale last spring ended with a raid he led in a hotel room and a long steady shot of agents falling out the window, dropping dead into a pool of water against a backdrop of blue sky and "When the Man Comes Around" by Johnny Cash.
The window drops, ever so slightly.
Trimming of reads was performed with trimmomatic (Bolger et al. 2014) using the minimum quality filtering (Phred 20) functionality of this tool with a sliding window, which scans through reads from the 5′ end and removes subsequent bases from the 3′ end once the average quality score within the window drops below a user-specified value (minimum size 50 bp).
"Only a real diamond will cut a glass window!" Drop hints with food: 1.
The process_radtags.pl program examines each read using a sliding window: if the average quality score within a window drops below 90% confidence [a Phred score of 10, Ewing and Green (1998)], Stacks discards the read.
Therefore we used Trimmomatic version 0.27 (Lohse et al. 2012) to; (1) remove the first 15 bp of each read, (2) trim any Illumina adapter sequence, (3) trim the 5′ and/or 3′ end of reads where quality score dropped below Q20, (4) trim anywhere within each read where a 5-bp window drops below Q20, and (5) discard any trimmed reads less than 36 bp long.
Therefore, we used Trimmomatic version 0.27 (Lohse et al. 2012) to trim or delete the following: 1) The first 15 bp of each read, 2) any Illumina adapter sequence, 3) the 5′ and/or 3′ end of reads where quality score dropped below Q20, 4) anywhere within each read where a 5-bp window drops below Q20, and 5) any trimmed reads less than 36-bp long.
