checkReliability()¶

checkReliability(main_col, rel_col, match_arg, time_tolerance, dump_file)¶

Compares two Datavyu columns to check for reliability errors and accuracy.

Parameter	Type	Description
main_col	String or Ruby variable from getColumn()	The primary column that rel_col will be compared against
rel_col	String or Ruby variable from getColumn()	The reliability column to compare to main_col
match_arg	String	The argument used to match the reliability cells to the primary cells. Must be a unique identifier between the cells.
time_tolerance	Integer	Amount of slack permitted, in milliseconds, between the two onset and offsets before it will be considered an error. Set to 0 to tolerate no difference.
dump_file	String path or Ruby File object (optional)	The full string path to dump the reliability output to. This can be used for multi-file dumps or just to keep a log. You can also give it a Ruby File object if a file is already started.

Returns

Console and file output.

Example

The following example checks the reliability column “rel_trial” against the primary column “trial”, linking the two on their “trialnum” code, with a 100ms onset and offset difference tolerated.

checkReliability("trial", "rel_trial", "trialnum", 100)

Example

The following example performs the same operation as the previous example, but also writes the output to ~/Desktop/Relcheck.txt, a text file.

checkReliability("trial", "rel_trial", "trialnum", 100, "~/Desktop/Relcheck.txt")
