 ### Changed
 
-- The swith for calculating Individual FD is arraged for each measurement area.
+- The switch for calculating Individual FD is arraged for each measurement area.
 
 - The setting for velocity calculation is changed in inifile. Now velocity can be calculated by projecting to any direction by setting the parameter `set_movement_direction`. The backward movement against the target direction can be considered or removed by setting the parameter `ignore_backward_movement`.
 
 - The way for reading .txt format trajectory file is changed. Now the order of each column in trajectory file is not so important. The trajectory file from JPScore can be analyzed directly.
 
-- The algorithm for loading the '.txt' format trajectory file is modified. Now the order of each column in the file is not so important. JPSreport will search for meaning of each column from the comments (for example"#ID FR X Y Z VD").
