Hi,
Do anybody mind to share that what is the "best" or "suitable" input file for genome size estimation program such as Jellyfish?
I still confuse should I used original raw sequencing read, pair-end data after preprocessing analysis (trim adaptor, remove low quality read, remove duplicate read, etc), or pair-end + single-end data after preprocessing analysis (trim adaptor, remove low quality read, remove duplicate read, etc)?
I have try the above 3 different data as an input file for Jellyfish by using 17-mer.
My data set is novel isolated bacteria.
Thus I not too sure what is the exact genome size.
The peak of 17-mer frequency (M) in reads is correlated with the real sequencing depth (N), read length (L), and kmer length (K), their relations can be expressed in a experienced formula: M = N * (L – K + 1) / L.
All the above 3 different data set gives me different peak of 17-mer frequency.
Thus it effect the calculation of genome size too.
Thanks for any advice.
