Hi Michelle,
I'm not surprised to hear that changing the basecaller made a big difference. I
know that some TTE protocols call for the ABI50 or SemiAdaptive basecaller, but we
find that the ABI LongRead basecaller (LR-377) works much, much better. We found
the others require too much hands on adjusting (changing the start point, the
spacing, etc.).
