Forward and reverse reads in paired-end sequencing

When you align them to the genome, one read should align to the forward strand, and the other should align to the reverse strand, at a higher base pair position than the first one so that they are pointed towards one another. This is known as an "FR" read – forward/reverse, in that order. This is all for conventional paired-end sequencing.

What is the Forward Current, I F, of an LED?

The forward current of an LED, IF, is the current which flows across the LED''s leads, from anode to cathode, in order for the LED to receive sufficient current to power on.. As you can see above, positive voltage must be applied across the LED from its anode to its cathode. This leads to a forward current across the LED leads from anode to cathode.
