File Name Substitution

Whenever a file name is required to load or save data, the following system is used. First, on startup, TkMedit attempts to acquire a User Home Directory and a Subject Home Directory. The User Home Directory is always the current directory from which TkMedit was launched. The Subject Home Directory is based on the way in which the anatomical data was loaded. If the default TkMedit loading method is used, it is the concatenated contents of $SUBJECTS_DIR and the subject name. If the -f switch is used, it is the value of that parameter.

If the first character of the file name is ~ (tilde) or . (period), it is substituted with the Subject Home Directory or User Home Directory, respectively. If the first character is another alphanumeric character, a default location directory is prepended to the file name. If the first character is / (slash), it is left alone.
