Hello everyone, I have a file which contains (something like this):
(MM):2:scurrent:OOTr1:t:0:c:-6.09249419808415990234375000e+00:
(MM):2:scurrent:OOTr1:t:1:c:-1.504382440400277657500976562e-01:
(MM):2:scurrent:OOTr4:t:0:c:-1.8307473939608802050712500000e-09:
(MM):2:scurrent:OOTr4:t:1:c:-2.0431058377931707220459843750e-01:
(MM):2:scurrent:SOTr1:0:t:0:c:1.405659077717170715332031250e-01:
(MM):2:scurrent:SOTr1:0:t:1:c:-1.492715471683210969543457031e-02:
(MM):2:scurrent:SSTr1:0:3:t:3:c:-4.365555129264354705810546875e-03:
(MM):2:scurrent:SSTr4:0:4:t:0:c:-3.780450239996445175595703125e-01:
....
and I would like to read from it only the bold face quantities and make three matrices which correspond to these columns. How can I do that?
Thanks in advance!

hello
here you are :
T = readlines('data.txt');
for ci = 1:numel(T)
Tci = T(ci);
str1{ci,1} = char(extractBetween(Tci,':scurrent:',':t:'));
num1{ci,1} = str2num(extractBetween(Tci,':t:',':c:'));
tmp = findstr(Tci,':');
Tcic = char(Tci);
num2{ci,1} = str2num(Tcic(tmp(end-1)+1:tmp(end)-1));
end
Out = [str1 num1 num2];
% will give following results :
% Out =
%
% 8×3 cell array
%
% {'OOTr1' } {[0]} {[ -6.0925]}
% {'OOTr1' } {[1]} {[ -0.1504]}
% {'OOTr4' } {[0]} {[-1.8307e-09]}
% {'OOTr4' } {[1]} {[ -0.2043]}
% {'SOTr1:0' } {[0]} {[ 0.1406]}
% {'SOTr1:0' } {[1]} {[ -0.0149]}
% {'SSTr1:0:3'} {[3]} {[ -0.0044]}
% {'SSTr4:0:4'} {[0]} {[ -0.3780]}
