Hi..Is there any way to open .MAX extension file in matlab.

please help me to open .MAX extension files.

[Walter Roberson]

is that related to 3DS Max models ? The more common extension for those is .3ds

Hi sir, it is not related to 3DS Max. it is ECG plot which is saved in .MAX extension. i have to extract that ECG plot data.

thank you...

I was not able to find any data on this format. I only found about two references to the format existing at all.

samples are attached here please go through it sir, and please provide help to resolve that.

thank you

There are character strings describing fields inside the file, but the character strings are variable length and do not appear to have a length count before them, so detection of \0 would have to be used to find their end. The format for any accompanying binary data for each field is not obvious.

I googled for a couple of the unusual strings, but I was not able to find any -- so if there is documentation then it is hidden away. I do not know enough about the topic to understand what most of the fields might mean, so I do not know what kind of values to expect in order to poke around to trying various binary conversions.

What kind of device (including manufacturer?) produced these files?

thank you..

ya.. because of combination, it felt difficulty to read.

If this is not a standard file format that MATLAB or another MathWorks product contains a function to read (which I believe is the case here) you have a couple options.

1. Ask the author of the code/program that wrote the file to provide you with a function to read the file into MATLAB.
2. Ask the author if they have code in some other language (C, C++, Fortran, Java, etc.) that you can call from MATLAB. See the "Using External Libraries" and "MATLAB API for Other Languages" sections on this documentation page for more information.
3. Ask the author of the code/program for the specification of the file format and use the file I/O capabilities of MATLAB to write your own reader function. This may require you to use the low-level file I/O functions.
4. Reverse engineer the specification of the file format and write your own reader function. This could be very difficult without some sort of Rosetta stone.
5. Hire a consultant to do 3 or 4.
6. Use the program that originally wrote the data to write the data to a new file in a standard file format for which a reader function already exists.

thank you sir.. I will go through it
