Building blocks
Building blocks page is an internal collection that can contain several molecule lists, i.e., building blocks, and these blocks are accessible for all user. Only administrators can make changes on this page, such as creating new blocks, renaming them, adding tags and descriptions, adding structures to a block by drawing or by uploading from file, editing or removing molecules, or deleting existing blocks.
To access the Building Blocks Collection, go to .../building-blocks, for example https://ps-demo.chemaxon.com/#/building-blocks in case of our demo site.
