WebRaw data is examined to ensure: quality scores for base calls are high, the GC content matches the expected distribution, short sequence motifs are not over-represented, and the read duplication rate is acceptably low. Several software options exist for sequence quality analysis, including FastQC and FaQCs. WebNov 21, 2014 · Our guess was that the GC bias of the adapter ligation kicked somehow in, and ruined the dataset. The supplier doesn't know what happened. I'm not sure if that could be the case here, because I don't know if you have biological differences within the DNA in your sample, but is probably worth checking. standonn Member Join Date: Nov 2014 … gmc trucks for sale in bowling green ky https://sluta.net
