I have a txt file with a repeated pattern as follows, (3 lines to be skipped, 4 lines information to be read, ...)
00-00:00:17.170 : Starting Dose with 1000 cycles
00-00:00:17.228 : Starting Pump motor.
00-00:00:17.328 : Stopping Motor
Dose Cycle = 1
Dosing Time (ms) = 5700
Start Pressure = 0.08
End Pressure = 0.00
00-00:00:17.170 : Starting Dose with 1000 cycles
00-00:00:17.228 : Starting Pump motor.
00-00:00:17.328 : Stopping Motor
Dose Cycle = 2
Dosing Time (ms) = 5800
Start Pressure = 0.98
End Pressure = 0.00
.
.
.
My current code only reads 1 block,
fid = fopen('nums1.txt');
for k = 1:3
tline = fgets(fid);
end
while ischar(tline)
C = textscan(fid, '%s %f', 'Delimiter','=');
tline = fgets(fid);
end
how can I repeat it for next blocks (I have about 400 blocks)? I want to get a results as this:
C{2} = 1
5700
0.08
0.00
2
5800
0.98
0.00
Does anyone have any suggestion?I'd appreciate that.

Following is a possible solution for your usecase:
fid = fopen('nums1.txt');
tline = fgets(fid);
counter=1
while ischar(tline)
if(mod(counter,7)>=4)
if(counter==4)
C = (textscan(tline, '%s %f', 'Delimiter','='));
else
C = [C ; textscan(tline, '%s %f', 'Delimiter','=')];
end
end
counter=counter+1;
tline = fgets(fid);
end
% C(:,2) will return a cell array containing the required result
