Loading .mat Error in Matlab 64 bit in Linux

Dear Mathwork Community,

I am using Matlab R2011b (7.13.0.564) 64-bit in Linux environment. I have saved a workspace (.mat) in version 7.3. The error started when I try to load this .mat file and it is unable to do so, giving error log below. Any idea where I could have made a mistake?

Thanks for your time.

To cross-check: are you loading the file on the same system and same MATLAB version as was used to create it?

[James Ooi]

Yes. I m saving the file on the same system using the same MATLAB version.

The system I am using is a cluster computer where there is 96 slave nodes and one master node where the jobs are launched.

Sorry for mentioning the obvious: Your MAT-file is damaged.

Either the saving failed, or the file was modified later, or your harddisk is dying.

[James Ooi]

That was my first thought, the .mat was corrupted.

Hence I copied it to my windows machine and it it loads fine on the Matlab Windows environment of the same Matlab version.

The file has to be transferred from slave nodes to master nodes for -append to the main .mat file. But this has been done successfully on my windows workstation.

I just thought someone in the community might have seen this sort of error log. Looks like its not fairly common.

Thanks anyway!
