SOAPdenovo statistics output for Nx

1
Here's the Nx output that I have got on running SOAPdenovo. Does column 2 represent L50 and column 3 N50?? Please clarify.

N10 2252 11403
N20 1611 29595
N30 1239 53911
N40 982 84988
N50 781 124052
N60 621 173134
N70 489 235218
N80 382 314436
N90 196 433979

General statistics are as follows:

Contig_Num 694440
Mean_Size 491
Median_Size 350
Longest_Seq 30470
Shortest_Seq 116

SOAPdenovo statistics file represents 3 column namely:

- 1st column represents : N10, N20, N30, N40, N50 .....N90
- 2nd column represents : Respective values of N10 ....N90
- 3rd column represents : Respective values of L10...L90 i.e Number of scaffolds whose length sum help fulfilling the 2nd column values

For instance, in your case:

- N10 value is 2252 and 11403 are the smallest number of contigs/scaffolds whose length sum N10 value and thus it represents L10
- N50 value is 781 and 124052 are the smallest number of contigs/scaffolds whose length sum N50 value and thus it represents L50

So, it is opposite of what you are thinking.
