Hi Nanfang,

Thank you for your reply. 

I thoroughly checked both SDM table with its corresponding .txt files and the entries in it to determine whether there is any missing values. But, the files seem to be fine and I could not see any missing variables in the SDM table or values in .txt files. 

I attached the .SDM table screenshots for your reference.  

It would be thankful if you could inspect them and guide me further. 

Thanks,
Best,
Karthik.
