trouble loading EBSD map

[Patcurran]

Hi,

I am trying to load an EBSD map into my Jupyter Notebook, I have one EBSD map (A3_zone1) which loads with no issues, but when i try to load a different EBSD map (A3_zone3) i get the error below. I believe it is because i updated my Aztec Crystal and so the .CPR file has a different format? - but not sure.
As far as I can tell there is nothing wrong with my EBSD map (A3_zone3), it opens in Aztec Crystal and MTEX

i am unable to upload the EBSD data as : 'we don't support that file type', please feel free to message me so i can send over the ebsd files

from defdap import quat
from defdap import ebsd
from defdap import hrdic


# Load in EBSD map
EbsdFilePath = "../EBSD_data_2/CP large area/A3_zone3"
#EbsdFilePath = "../EBSD_data_2/CP large area/A3_zone1"
EbsdMap =  ebsd.Map(EbsdFilePath)
#EbsdMap.rotateData()```

Error message:

Hi Patrick,
You're using the develop version here right? Can you try to load the file with the current release version and see if that works. The loader in the master version is tolerant of unknown data in the file. If that works I'll update the loader in the develop branch for you.

hi Mike, yeah I am mainly using the Dev version but i have just run it on the masters version and it did work. I might just update my defdap to the master version.

thanks for your help !
