I was trying to recalculate the RIN value using the Agilent Bioanalyzer. because it couldn't calculate the RIN value due to 'unexpected ribosomal ratio' error flag. I checked the setpoint for the ribosomal ratio for RIN calculation and it was 0.7. I then edited the fragment size of the 28s and got a ratio of 1.1 but still the error says the same and no RIN value. So, does that mean it is impossible to recalculate the RIN value? Thanks in advance for your kind help.
