Hi, I have a 20 minute video recording of an insect and i need to process it. Since it is the raw data,its file format is .seq.
Can anyone help me in reading the seq file in matlab?
Thanks

Was your .seq file created by Cyberpaint or by NorPix ?

There must be a problem in reading the header. The ImageWidth shown there happens to correspond to hex 0x18171918 which is entirely too regular to be an accident.

There are some routines for working with .seq files in MATLAB. I've not been able to test them.

Hi, Thanks for reply.Unfortunately none of those codes are working. I guess those codes are meant for reading the sequential files which are often generated during the sequence analysis of DNA/RNA etc which are text files. But in my case, these .seq files are raw video files.
I am unable to read this file in MATLAB using any of the reader. Please provide some solution. Thanks

You can now read compressed and uncompresed sequences completly, or within a reading window with the above script.
