How to use the DECIMER web app?
Just upload a pdf document or one or multiple images that contain chemical structure depictions above. If a pdf document is uploaded, DECIMER Segmentation is used to detect and segment all chemical structure depictions. The detected or uploaded chemical structure depictions are processed using the powerful OCSR engine of DECIMER V2. The chemical structure depictions and the corresponding SMILES representation are presented above. You can edit the structures according to your needs in the Ketcher chemical structure editor windows before downloading the segmented images and the correponding mol files. Additionally, the IUPAC names of the chemical structures can be resolved using STOUT V2.
