= Name =
mri_mergelabels

= Description =
This is a simple script that will merge two or more label files. It does this by catting the label files together (after removing the first two lines). It inserts a new header (the first two lines). The number of entries in the new file (ie, the number on the second line), is computed by summing those from the input files.

= Synopsis =
mri_mergelabels -i <label1> [-i <label2> ...] -o <outputlabel>

= Arguments =
|| -i label || input label ||
|| -o outputlabel || output label ||
|| -d dir || all labels in a directory ||

= Label File Format =
Labels are simple text files. The first line is a header. Each following line contains data with 5 columns. The first column is the vertex number of the label point. The next 3 columns are the X, Y, and Z of the point. The last can be ignored. If the label is not a  surface-based label, then the vertex number will be -1.
