### Description

For statistical analysis and filtering the measurements need to be annotated with Filename, Condition, BioReplicate, and Run. This functions takes this information from a txt file containing this meta-data.

    column.file = "filename", change.run.id = TRUE, verbose=FALSE)

### Arguments

`data` | A data frame containing SWATH data.
`sample.annotation` | A data frame containing the columns: Filename, Condition, BioReplicate, Run. The values contained in the column filename have to be present in the filename of the SWATH data.
`data.type` | Option to specify the format of the table, if the column names from an OpenSWATH output or MSstats table are used.
`column.file` | Option to specify the column name where the injection file is specified. Default is set to "filename".
`change.run.id` | Option to choose if the run\_id column shall be reassigned to a unique value combining the values of Condition, BioReplicate and Run. (Option only possible if data is of format "OpenSWATH")
`verbose` | Option to turn on reporting on which filename it is working on.
