It seems that this file is not supported, can you please share a file that we can use to reproduce and test?
Thank you for the response. Please find the file (Test.map) inside the following .zip file
Is the size of image fixed with 256x256 pixels? Is there another file that was saved with *.img file?
This test file contains 32 bytes header: 00000000 01 00 00 00 00 00 00 00 00 00 00 00 08 00 00 00 |................| 00000010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................|
And also 256x256 pixels double precision float values (8bytes / pixel). 00000020 00 00 00 00 00 cc b1 40 00 00 00 00 00 c0 b1 40 |.......@.......@| ....
We need more sample data to resolve this issue. Do you have some related metadata files with this map?
@PereraUmesha, would you be able to provide the information asked by @nem1234? Thanks!
Describe the bug
I am trying to load a .map file from JEOL's EPMA (Electron Probe Micro Analyzer). Then I get the below error.
WARNING:hyperspy.io_plugins.jeol:Not a valid JEOL img format ERROR:hyperspy.io:If this file format is supported, please report this error to the HyperSpy developers.
