# Manual Correction Quantitation

In some cases it will make sense to adjust your quantitation by a factor which can't be calculated from within SeqMonk. You may have other experimental data from outside the sequencing experiment which you want to use to correct your quantitated values.

The manual correction quantitation allows you to adjust some or all of your quantiations by supplying a user-defined correction factor for your data.

## Options

- What type of correction to apply (add, subtract, multiply, divide)
- A correction factor for each currently quantitated data store. Any stores where a factor is not supplied will be left with their original quantitation values
- Instead of entering your correction values manually you can also opt to load these from a file. This must be a tab delimited file where the first colum is the data store name (which must match exactly) and the second column is the correction value you want to use. These will then be loaded into the options panel to save you a load of typing.
