Extract every 2,6,10 and 3,7,11 line irrespective of data type from text file using matlab

Hi Friends,

It has been hours since I am trying to find out the solution of above problem . Unlike other file I could extract entire depending upon a particular string present in the data which is almost 40000 rows . But here file is different.

   Time(sec) 20.30
   Type 1
   Svid  slew  power used 
   12.    0.33 -36dbm y
   10     .38. -40dbm N
   08.    0.40 -30dbm Y
   Time(sec) 20.40
   Type 2
  Svid  slew  power used 
  12.   0.46. -38dbm Y
  06.   0.50. -32dbm Y
  02.   0.42. -30dbm N

Now I want to pull out all Type

 1 svid 12 rows

from entire file. these svid is repeated after particular index so as other svid. I want to extract any of this sv Id. Any type of suggestions is highly appreciated.

Thanks

Poka

The question is not clear and really hard to read. Please use the standard formatting in the forum as the other contributors do. Mark clearly, where the input file is and what the text of the question.

I do not understand what e.g. "Now I want to pull out all Type 1 svid 12 rows" means.

I think it means all of the rows in an Svid section where the first column is "12.", and the number on the Type line for the section was 1.
