MpRester.query() is replaced with MpRester.summary.search()

[karthiCk396]

Describe the bug
Before I used the MpRester.query() to download and access the all elements in the Material project but it changed to MpRester.summary.search() so I could pass the mongoDB query to download and access all the elements with properties = ['cif]

Can someone suggest a command or query to download and access the all elements in the periodic table as cif file (using python /pymatgen).

Thanks in advance

Hi @munrojm, I can not open this link, what should I do now,Wish you can help me out, Thanks

@munrojm Thank you for reply. This will help me definitely. Do I able to access all the elements of periodic table in single query instead of accessing the single element ?

[munrojm]

If you would like to query structures containing any element, simply remove the elements argument and only pass fields to search. It will default to querying structure data for every material in the database.

Thank you @munrojm . It's working.

@munrojm I have another doubt . How do I get the band gap value for the each element from the structured data of material

[karthiCk396]

I have used the below query to access the all elements with structure and band_gap fields.

results = mpr.summary.search(fields= ['structure',"band_gap"]) and converted into CIF file. After converting into the CIF file I have resued the cif file and trying to access the structure and bandgap. But I'm only able to access the structure but I'm not able to access the bandgap

and I used the function to get structure . struct1 = struct.get_structures()[0]

can anyone help me out in getting the bandgap from the structured data ?

[munrojm]

To clarify, you want the element projected band gap for each material?

Yes @munrojm . I figured it out. Thank you for your time and help.
