It's possible to upload a structure (EICs will be created automatically) either to individual injections or to many injections at a time in a Batch. Possible options:
namefield (optional) will be used for the alias of the structure
injectionfield (optional, Batch level) determines which injections receive the structure
You can either upload/drag'n'drop files or just copy-paste their content directly into Peaksel forms. See demos below.
