Problem with unichem.structure

[sbgsbc]

I'm enabled to get an answer to :

  from chembl_webresource_client.unichem import unichem_client as unichem

  ret = unichem.structure('AAOVKJBEBIDNHE-UHFFFAOYSA-N', 1)

Answer is :

MaxRetryError: HTTPSConnectionPool(host='www.ebi.ac.uk', port=443): Max retries exceeded with url: /unichem/legacy/rest/structure/AAOVKJBEBIDNHE-UHFFFAOYSA-N/1 (Caused by ResponseError('too many 404 error responses'))

But

  ret = unichem.get('AAOVKJBEBIDNHE-UHFFFAOYSA-N', all=True)

is fine.

Is there a problem with the structure() method ?

I'm using chembl_webresource_client 0.10.8 installalled from conda-forge.

Many thanks.

Hi Stephane,

The unichem.structure function reutrns the structure for a given pair of source compound id and source id:

from chembl_webresource_client.unichem import unichem_client as unichem
ret = unichem.structure('CHEMBL12', 1)
print(ret)

[{'standardinchikey': 'AAOVKJBEBIDNHE-UHFFFAOYSA-N',
  'standardinchi': 'InChI=1S/C16H13ClN2O/c1-19-14-8-7-12(17)9-13(14)16(18-10-15(19)20)11-5-3-2-4-6-11/h2-9H,10H2,1H3'}]

Hi, Thanks to answer so quick : I tried from chembl_webresource_client.unichem import unichem_client as unichem ret = unichem.inchiFromKey('AAOVKJBEBIDNHE-UHFFFAOYSA-N') print(ret) The result is : [{'standardinchi': 'InChI=1S/C25H23F3N4O2/c26-25(27,28)21-9-4-20(5-10-21)8-13-24-30-22(18-34-24)17-33-23-11-6-19(7-12-23)3-1-2-15-32-16-14-29-31-32/h4-14,16,18H,1-3,15,17H2/b13-8+'}] So the connexion seems to be ok. If I try your code from chembl_webresource_client.unichem import unichem_client as unichem ret = unichem.structure('CHEMBL12', 1) print(ret) After 12 s I obtain the following error :

which version of the library are you using? could you please try with the latest one? 0.10.8

[sbgsbc]

I’m using 0.10.1. I’ve switched to 0.10.8 and some tests are conclusive. It seems OK. Many thanks.
