You have imported a compound library, and you usually add a new column during import containing a user-defined field, or batch field. During the latest import you forgot to include this field. What can you do now to update your recently imported library?
This is easy enough to fix. Simply download Registered molecules from the file's validation report. Remember that all historical validation reports are found under Import Data tab -> Previously Imported Data -> Report link for the specific file.
Now import this file right back, mapping only Molecule name, and Batch name. If the field or column you accidentally left out is part of the file, map this column too. If you were planning to create this column on the fly using CDD's mapper, do it now. Process the file as usual.
