Finding multiple Matrix in a txt file

I want to do radiobiological calculations for structures in a patient with two different plans. I have a txt file with all the data in it. The txt file contains among other things the biological structure (which exists in both plans), the biological data in two columns and two rows that specifies what plan and what structure it is.

I know how to code the math to do the calculations, but how do I most easy read the text file and store each plans column in like a matrix?

For example (in my own dumb coding brain) I would like matlab to "Search a txt file that has a certain name that the user can specify. For a specific organ like the bladder, put the data in a variable called something like "Bladder Plan 1" and "Bladder Plan 2". Do math. Do same for all other organs. Put result in a report. Save as pdf or file". I hope that the wonderful Matlab community can help me, since I am no Matrix wizard with coding.

For all patients the structures all have the same naming convention, so I guess I could specify somewhere/somehow what organs should be searched for in the text file and what I would like the variable to be called, so that the search in the text file could go quick.

If anyone has any tips and suggestions that would be great. I have attached an anonymized txt file of how it could look like.

It will take a fair amount of parsing the file -- probably by searching for keywords because it appears the length of the file(s) may be different given that the Comment and Description fields almost certainly can't be assumed to always have the same number of lines so fixed lines for a given variable won't work.

That's not too bad, but it does mean having a dictionary of the things you need to locate stored somewhere; either as constants in the code or as a data file that you read in and use.

Do NOT try to go down the route of trying to name variables; that leads to very difficult-to-write (and even harder to debug) inefficient and slow code. Instead, use struct field names that are able to be coded programmatically. See <Structures>, particularly relevant will be the section on field names from variables.

"For example (in my own dumb coding brain) I would like matlab to "Search a txt file that has a certain name that the user can specify. For a specific organ like the bladder, put the data in a variable called something like "Bladder Plan 1" and "Bladder Plan 2"."

Rather than "searching" a file for particular content I would convert the entire file content in one go. "Searching" in a table is likely going to be simpler and more efficient:

txt = fileread('Breast.txt');
tkn = regexp(txt,'(Structure:.*(\s+.+:.*)+)\s*:\s+(.+\])\s*(.+\])(\s+\S*\d\S*)+','tokens','dotexceptnewline');
tkn = vertcat(tkn{:});
hdr = regexp(tkn(:,1),'(\S.+):(.*)','tokens','dotexceptnewline');
out = hdr;
for k = 1:numel(hdr)
    % header
    tmp = strtrim(hdr{k});
    tmp = vertcat(tmp{:});
    vec = str2double(tmp(:,2));
    idx = ~isnan(vec);
    tmp(idx,2) = num2cell(vec(idx));
    hdr{k} = cell2table(tmp(:,2).', 'VariableNames',tmp(:,1));
    % matrix
    mat = sscanf(tkn{k,end},'%f',[2,Inf]).';
    out{k} = array2table(mat, 'VariableNames',tkn(k,2:3));
end
hdr = vertcat(hdr{:}) % all headers in one table:

hdr = 36x21 table

Answer 2

[Star Strider]

This works. It is not as elegant as I would like, however I cannot imagine any other way to parse this file.

The variable names are some subset of ‘Dose [Gy] dVolume / dDose [cm² / Gy]’ however I cannot figure out how to parse that into two variable names for the ‘Tseg’ tables.

Try this —

T = fileread('Breast.txt')

T = 
    'Patient Name         : 
     Patient ID           : 
     Comment              : DVHs for multiple plans and plan sums
     Date                 : den 16 maj 2024 07:29:00

EDIT — (12 Aug 2024 at 19:25)

Updated code to use textscan, and it now runs without error. (The previous problem was in reading the exponential notation.)

EDIT — (12 Aug 2024 at 23:25)

Corrected initial comments, since I got it to work correctly (albeit not elegantly) with textscan.

"...cannot figure out how to parse that into two variable names for the ‘Tseg’ tables."

One way, albeit not extremely elegant...

T = fileread('Breast.txt');

idx1v = strfind(T, 'Dose [Gy] dVolume');
idx2v = strfind(T, '45.25');
idx3v=strfind(T(idx1v(1):end),char(10));
vstring=strip(T(idx1v(1):idx1v(1)+idx3v(1)))

vstring = 'Dose [Gy] dVolume / dDose [cm³ / Gy]'

vnames=cellstr(extractBefore(vstring,' dV'));
vnames{2}=strip(strrep(vstring,vnames,''));
vnames(2)=strrep(vnames{2},' / ','/')

vnames = 1x2 cell array
    {'Dose [Gy]'}    {'dVolume/dDose [cm³/Gy]'}

In general, I think one would need to also return the structure and the plan with the data for any context at all; just having by order in the file is going to be very hard to keep straight...nor that you aren't aware of that, @Star Strider, just commenting to @Carl Magnus I think will still need to parse fields in the file for identification purposes.
