Advanced Import makes it possible to create any job (and import it into the database) from individual files.
JOBS experiments have a complex structure which typically cannot be entirely inferred from the files being imported. Therefore the import consists of telling the program the missing information.
Especially the order of experiment (loop sequence and their nesting) must be defined in such a way that each frame from every file has its defined place in the sequence.
Furthermore, not all important metadata can be derived from the image files (such as well-plate name, barcode, XY positions, wavelengths, etc.). As such metadata is typically related to the loops (plates, wells, Z-stacks, time-lapses, etc.) and repeat as a result of looping it is convenient to define them together with relevant loops.
Advanced Import extends ordinary Import which is limited to experiments contained inside the single ND2 file, where all data is present.
