Good morning.

I have series of data in cvs file like below,

1,,,

1,137.1,1198,1.6

2,159,300,0.4

3,176,253,0.3

4,197,231,0.3

5,198,525,0.7

6,199,326,0.4

7,215,183,0.2

8,217.1,178,0.2

9,244.2,416,0.5

10,245.1,316,0.4

I want to extract specific data from second column for example 217.1 and 245.1 and have them concatenated into a new file like,

8,217.1,178,0.2

10,245.1,316,0.4

I use cvs module to read my cvs file, but, I can't extract specific data as I desire. Could anyone kindly please help me. Thank you.
