NF is the number of fields.

If T is greater than 80% of NF, print.

Output will be as follows.
Code:
        sample1 sample2 sample3 sample4 sample5 sample6 sample7 sample8 sample9 sample10
v5    0.1     0.1     0.2     0.2     10      2       3       5       6       7

Is it possible to extend the same code but calculating 80% in each group separately like the flowing

Input

Code:
        group1  group1  group1  group1  group1  group1  group1  group1  group1  group1  group2  group2  group2  group2  group2  group2  group2  group2  group2  group2

That certainly is possible.
Why do lines v2, v3, v4 show up in your sample output?
Are there always two groups? Of identical length?
What be the exact condition for when to print and when not?

Old 02-23-2015
oops. I corrected it now. So each value should be greater than 0.1 in 80% of the samples in at least one group. Ex: V4 satisfy this condition in group2 and V5 in group1.

Hello quincyjones,

I think output should be v1. Following may help you in same, please let me know if this helps.
Code:
 awk '{for(i=2;i<=11;i++){if($i > .1 && $(i+10) > .1){T=1}};if(T){print $0;T=""}}'  Input_file

Output will be as follows.
Code:
        group1  group1  group1  group1  group1  group1  group1  group1  group1  group1  group2  group2  group2  group2  group2  group2  group2  group2  group2  group2
        sample1 sample2 sample3 sample4 sample5 sample6 sample7 sample8 sample9 sample10        sample1 sample2 sample3 sample4 sample5 sample6 sample7 sample8 sample9 sample10
v1    0.2     0.1     0.1    0       1       2       3       4       9       10 0.2     0.1     0.1    0       1       2       3       4       9       10

EDIT: Sorry typo here changed the output now.


Thanks,
R. Singh

It is v4 and v5. Because v1 has three samples of either group 1 or group2 have values have <=0.1 (so it doesn't satisfy the condition "greater than 0.1 in at least 80% of the samples in a specific group). Hope that is clear.
