### Arguments

`batch` | Character string, this refers to the name of a collection of experiments.
`attri` | Character string, the name of the information to be included in the data structure. For example, from the output of tt{Spot}, this argument can be "area", "signal to noise" etc. In other words, these are the column headings from the raw data set.
