Some OCHEM models (e.g. models aggregated using Bagging method), require significant amount of calculations. |
Way 1: "Request until done"
To post predict a prediction task for a molecule, run the following request (as example):
https://ochem.eu/modelservice/getPrediction.do?modelId=YOUR_1&mol=c1ccccc1
It will predict mutagenicity of benzene (c1ccccc1 is MOLECULE) using the AMES model https://ochem.eu/model/1 (1 is MODEL_ID)
In general your request should have form https://ochem.eu/modelservice/getPrediction.do?modelId=MODEL_ID&mol=YOUR_MOLECULEModel id MOLECULE where MODEL_ID is the public model identifier or "model identity" (GUID) provided by OCHEM administration. If you plan to use predictions systematically, it is recommended to request a model identity (GUID).The molecule and MOLECULE is the analyzed molecule.
The MOLECULE can be in SMILES or SD format. For both the formats, multiple molecules can be posted using $$$$ separator.
It is much more efficient to predict molecules in batches rather than posting separate tasks for each molecule.

Another and a simpler way to get prediction is to use
...
request. You will get the same JSON results as above, but without a need to use explicitly taskId.
