Hi, I’m so sorry that I ask questions under very different issues!
I have tried to put the _codadef_ file into my share/coda/definitions, but it doesn’t work.
It gives the same error:
**coda\_open(): unsupported product file**
This is the code:
**import coda**
**import os**
**from numpy import vstack,zeros**
**os.putenv(‘CODA\_DEFINITION’, r’D:\yika\work\Aladin\coda\share\coda\definitions’)**
**product=coda.open(“AE\_OPER\_ALD\_U\_N\_2B\_20201008T233259\_20201009T010347\_0001.DBL”)**
I wonder if there is someway to check why it’s wrong or how to deal with it?
Thanks again and sorry again!

Can you open a dos/command prompt and run codacheck on these product files?
e.g. `codacheck -V AE_OPER_ALD_U_N_2B_20201008T233259_20201009T010347_0001.DBL`, `codacheck -V AE_OPER_ALD_U_N_2B_20201008T233259_20201009T010347_0001.HDR`
And let me know the output?
The codacheck executable should be in `D:\yika\work\Aladin\coda\bin`.

That looks Ok.
I already see what is going on. You need to call the `os.putenv` before you call `import coda`:
```
import os
os.putenv(‘CODA_DEFINITION’, r’D:\yika\work\Aladin\coda\share\coda\definitions’)
import coda
from numpy import vstack,zeros
product=coda.open(“AE_OPER_ALD_U_N_2B_20201008T233259_20201009T010347_0001.DBL”)
```
This should work.

hello sir. I also meet a similar problem.
I install coda 2.21.1 on the server via anaconda.
And try to run the sample program in github.
But it show me the error as yika64.
My error program as follows.
`import os
os.putenv(‘CODA\_DEFINITION’,’/student/home/chikiangtam/anaconda3/envs/aelous/share/coda/definitions’)
import coda from numpy import vstack, zeros
filename="/student/home/chikiangtam/aeolus/data/A2B\_20210504T085256/AE\_OPER\_ALD\_U\_N\_2B\_20210504T084256\_20210504T101320\_0001.DBL"
product = coda.open(filename)`
And i also try to use the codacheck to check out the DBL file,but it shows me that it is an unsupported product file.
I have placed the definition file in “/student/home/chikiangtam/anaconda3/envs/aelous/share/coda/definitions/”，and there are products/types/index.xml and tests.xml in the definition floder.
i wonder to know if some steps are still missing.
Thanks you very much!

You should not install the folder with xml files, but the .codadef file. You can find it as an attached for the [release](https://github.com/stcorp/codadef-aeolus/releases/latest).
