Hi all,

I am stuck on a problem in one of my scripts.
In this script I am using the textscan function to read a .txt file into an array.

The code I am using is:

fid = fopen(strcat(OPENPATH, FILENAME));
Data = textscan(fid, '%d64 %*s %d32 %*f %*f %f %f %*f %*f %*f %*f', 'headerLines', 23, ...
'treatAsEmpty', {'MSG', TRIALSEPARATOR}, 'emptyValue', 0);
fclose(fid);

If I read the following .txt data into this array, everything works fine:

Update after seeing how the message displays data:

note that the data as shown in the message is not exactly in the same format as the actual .txt files.

In both cases the 23rd line is:
0 SMP 0 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00

That's exactly the point, I don't know what the difference is.

Hi,

I simplified the question I am having, so someone hopefully can provide a solution.

The issue I am having with my textscan function is the following:

I am using this code:
------
fid = fopen(strcat('C:\test\', 'FILENAME.txt' ));
Data = textscan(fid, '%d64 %*s %d32 %*f %*f %f %f %*f %*f %*f %*f');
fclose(fid);
------

When using a txt file containing the following data, the variable Data ends up as it should:

29375 SMP 1 170.19 109.94 79 76 158.63 630.3 538.69 1

How3ver, when using this file, Data ends up as an 1x4 empty array:

15555 SMP 1 183.64 93.76 68 70 179.83 435.65 418.87 1

Hence my question, why? And how do I solve this?

thanks a lot in advance,
Steven
