Warning in ReadUff() Function

Dear Mr. Emmert,

I am using your ReadUff() Matlab function for testing the format for a uff58b type, which I programmed myself with vb.NET.

When reading the generated file with other software, it can be read without any warnings.

The ReadUff() function in matlab however throws the following warning for every set:

Warning: Badly formated binary uff file (TestData_58b.uff) at set #2: the size of the data is greater than the number of bytes specified; extra extra bytes at the end will

be skipped.

I tried several changes in my code, without any success.

I would be very happy about any hint.

Thank you very much !

Hello

can you send me your uff file so I can test it ?

cheers

This seems to relate to https://www.mathworks.com/matlabcentral/fileexchange/70464-uff-file-reading-and-writing

That section of code has the comment

        % It was observed that some programs write some inconsistent values
        % to the header concerning the number of data and/or bytes the data
        % is to occupy. In case such incosistency is found, the max number
        % will be used and a warning displayed.

so it sounds like a common problem that the header does not match the data. Other programs might choose not to complain about it, or might ignore the header when reading the file.

Thank you very much for your reply.

Attached you can find an example of my uff58b file in .txt format.

Best regards

@Walter Roberson,

thank you very much for your hint.

Lets say I have a set of 200 data (single precision) which means that the number of following bytes should be 200 * 4 bytes = 800 bytes right ?

I do not understand where the inconsistancy comes from.

Best regards

hello again

I could open succesfully your file using the attached readuff file

all the best !

clc
clear all

[UffDataSets, Info, errmsg] = readuff('TestData_58b.uff')
