Example

There is a some.csv.

Student,Reading,Writing,Math,Science,Social Studies
A,90,74,33,73,59
B,83,67,84,41,61
C,73,72,80,12,93
D,43,87,67,55,63
E,33,89,97,76,66

Then you wanna get the second Reading's statistics.

Just do it!

colc 2 some.csv

Of course -b,--binsize works well:)

colc 2 some.csv -b 25

There are noises, then filter necessaries(>=1%) with -f,--filter

colc 2 some.csv -b 25 -f 1

If you wanna check whether the file is valid in advance,

-c,--check answers the file is dirty or clean.

colc 2 some.csv -c
