I am facing this problem, ":bang was not loaded from the file" when i incerase lenght of variable in for loop, how can fix this

Caught "std::exception" Exception message is: Message Catalog MATLAB:bang was not loaded from the file. Please check file location, format or contents

Please show your code.

The similar questions that I find suggest that this error is very commonly the result of having fopen()'d too many files without having closed them. In some cases involving load() in a loop, the error has be in the MATLAB implementation in some versions.

actually i am using "load" inside the for loop, that is why facing this problem, but i don't know how to fix it ?

is any other way to load in loop?

Again: Please post the relevant part of the code, Pradeep Kumar. Without seeing any details guessing is rather hard.

[Walter Roberson]

Which MATLAB version are you using?

You might be able to add

close('all')

after you do the load(), but it is not certain that the file list known to close() would include all files opened internally by load()

for r=0.25:0.25:2

    for tm=1500:50:5500

        display('calling to susddevent code');

        ext=sprintf('Suaddevent_edited %f',tm);

        close('all');

        [data2,sutracehdr2,suhdr2]=ReadSu('cal.su');
        %system('close(all');
        close('all');

this is part of my code, where I am using ReadSu for loading the data'data.su' file

[Pradeep Kumar]

I am using 2013 version

ReadSu appears to be part of SegyMAT

A readable form of the source appears to be at http://www.codeforge.com/read/234771/ReadSu.m__html . If that is the version you are using, then it appears to that the code does not fclose(segyid) after it is done with it, so you would end up with this problem.

You should only need a single close('all') after the ReadSu

I notice, however, that in the code you present, you are always reading the same file. Are you also writing to the file in the loop? If the file is not being changed in the loop, then why not just read the data once and process whatever part of it is needed in each loop?

[Pradeep Kumar]

actually file data being change in each iteration,that is why it is necessary to read again and again
