SCINTILLAORS STACK WITH CHAMBER-1_21.txt

Dear Experts,

I want to read the values inside orange line as an array.

file name is " SCINTILLAORS STACK WITH CHAMBER-1_21.bnn.lis " which looks like in the image (file is attached which I can open in with .txt format as i couldn't attach the original .bnn.lis file).

I tried the following method but it is not giving the desired terms

filename='SCINTILLAORS STACK WITH CHAMBER-1_21.bnn.lis';

fileid=fopen(filename);

c=textscan(fileid,'%f %f %f %f %f %f %f %f %f %f %f %f %f %f %f');

fclose(fileid);

whos c

Please, help me take out the values inside the orange line

Thank you

hello

this is one possibility :

lines = readlines('SCINTILLAORS STACK WITH CHAMBER-1_21.txt');
%% main code 
nn = find(contains(lines,'accurate deposition along the tracks requested')); % find the line number of this text
lines_to_read = 2;  % read the 2 lines after line containing above text
for ck = 1:lines_to_read
    tmp = (str2double(split(lines(nn+ck))))';
    tmp(isnan(tmp)) = []; % remove NaNs
    out{ck,1} = tmp;  % store in cell array
end
% export to txt
writecell(out,'output.txt',"Delimiter","\t");
