Hello, I am trying to import this text file into matlab but only reading certain values. Ignoring the uncollided data, I want to be able to retrieve the location of each detector (x,y and z) , (z = 0 for all detectors). Also, I want to be able to retrieve the "total" value which can be found at the end of each collided data. I know this data that is being imported is very hard to convert to the values I need but I would appreciate any help. Thank you in advance.

If that is the case, try:
raw = fileread('D1output1.txt');
[~,tok] = regexp(raw,'x,y,z = (\d+\.\d+E\+\d+) (\d+\.\d+E\+\d+)(-\d+\.\d+E\+\d+)\s*\n\s(?!uncollided)','match','tokens');
data=[tok{:}];
x=str2double(data(1:3:end));
y=str2double(data(2:3:end));
z=str2double(data(3:3:end));

Sorry for the late reply, but when I tried running this code, I get the coordinates for each x and y as a matrix of 1x80 but there should be a total of 100 collided points, thus getting a matrix of 1x100. Do you know why this is the case?
