miRNAs annotation | |
|
The miR_name is composed of the known miR name in a cluster, an underscore, and a matching annotation such as | |
L− means that the miRNAs_seq (detected) is base less than known rep_miRSeq in the left side; | |
R− means that the miRNAs_seq (detected) is base less than known rep_miRSeq in the right side; | |
L+ means that the miRNAs_seq (detected) is base more than known rep_miRSeq in the left side; | |
R+ means that the miRNAs_seq (detected) is base more than known rep_miRSeq in the right side; | |
2ss5TC13TA means 2 substitutin (ss), which are at position 5 and at position 1. | |
The miRNAs_seq (detected) is exactly the same as known rep_miRSeq; miRNAs_name is the name of representative miRNAs. | |
