I used Geneious and codoncon Aligner programs to assemble my reads and I noticed that there was a slight difference in at least the beginning.
It's probably a difference in the quality cut-off by the different programs. The first ~50 bases are normally low-quality and will be trimmed off. The exact threshold varies by program.
I am wondering if kinematic viscosity measurements of crude oil be numerically extrapolated to obtain accurate values for higher and lower temperatures than the test range. Has anyone done this...
