Hello neeraj_kr,

Welcome to the Monastery. I am bit confused here. I am not sure through your code sample and description what you are trying to do.

Can you copy a few lines of input as a sample, and create a sample (hard-coded) of the desired output. I mean for example you have input:

0 2:-0.5795 3:0.33582025 4:55.8255 5:65.316997 6:15 7:16 8:57 9:28 10:
+29 11:23 12:5 13:4328.520884 14:5279.218852 15:7434.371708 16:7829.12
+6536 17:7560.24877 18:7380.518025 19:7094.262906 20:6916.621367 21:61
+98.40255 22:11858.88819484 23:15547.317962699 24:23174.9885578928 25:

Desired output would be:

2:-0.5795
3:0.33582025
21:6198.40255
23:15547.317962699

Something like that, of course the sample above it is just an example but at least to give us a direction of what you are trying to do.

Update: Based on your sample of code above your data is ' ' space separated but on your code you split the data with \t. Which one is the correct?

Looking forward to your update, BR.
