MetaTexis offers functions to check several formal aspects of a translation: number of words, number of characters, number of numbers, spell checking.
The formal quality checking options can be accessed via the General options dialog, tab Quality Check:
If the Check formal quality of translation units checkbox is checked, MetaTexis checks the formal quality of the translations compared to the source text.
If neither the After activating checkbox nor the Before closing is checked, the quality checks will only be performed when you execute a Go-to-command (see Go to Functions).
