Hi , i have theses data sets as text file,
i need extract and save specific rows only ( i need the rows that contains the words : ReadReq or WriteReq , ( otherwise negleget all other rwos !)
example: i need extrect the rows contain on the words inside its ( readReq or Writereq) such as :
3411151194500: system.cpu04.icache: ReadReq [380730:380733] IF hit state: 7 (E) valid: 1 writable: 1 readable: 1 dirty: 0 tag: 1c0
3411151194500: system.cpu04.dcache: WriteReq [a22a48:a22a4f] miss
from the original text file :
3411151194500: system.cpu04.icache: ReadReq [380730:380733] IF hit state: 7 (E) valid: 1 writable: 1 readable: 1 dirty: 0 tag: 1c0
3411151194500: system.cpu04.dcache: createMissPacket: created ReadExReq [a22a40:a22a7f] from WriteReq [a22a48:a22a4f]
3411151194500: system.cpu04.dcache: WriteReq [a22a48:a22a4f] miss
3411151194500: system.cpu04.dcache: recvAtomic: Sending an atomic ReadExReq [a22a40:a22a7f]
3411151194500: system.cpu04.dcache: Block addr 0xa22a40 (ns) moving from state 0 to state: 7 (E) valid: 1 writable: 1 readable: 1 dirty: 0 tag: 511

I'd recommend you go over the questions asked by this guy because I've answered several question of his that dealt with parsing log files very similar to yours.

% Read all your data into a cell array. 'Delimiter','' means to import
% everthing into one column, which I believe is better for your
% application.
data = readcell('data.txt','Delimiter','');
% Create a vector 'TF' that identifies logically which rows in 'data'
% contain the strings you identified. "|" represents the 'or' function.
TF = contains(data,('WriteReq')) | contains(data,('ReadReq'));
% for every element of 'data' where TF is zero (false, i.e. doesn't contain
% either string) set that value to '[]' to delete it from the array.
data(TF == 0) = [];
