Warn/fix unreasonble values for RNA remaining quantity in JSON files

[Nicklas Nordborg]

The JSON files that are imported by the "Import externally processed samples" wizard seem to have unreasonable value for the original and remaining quantity. It seems like only a few nanograms have been used in the library prep. The higher the concentration it seems like a lot less has been used. The values makes more sense if the difference between original and remaining quantity is interpreted as a volume (in µl).

Example, in the JSON we have:

• Original quantity (ng): 23980
• Remaining quantity (ng): 23978
• Concentration (ng/ul): 436

It is not reasonable that only 2ng was used, but 2µl*436ng/µl=872ng is more likely (though rounding the quantities to whole numbers probably affect the result).

The import wizard should check the original and remaining quantity and issue a warning if the difference is less than 100ng. It should also try to re-calculate the quantities based on the assumption that the difference is a volume in µl and if it makes more sense use that when importing instead.
