This new version of profile_read now changes ',' by '.' in strings before trying to convert them to numbers. The information about each channel
is now saved in a structure head.ch() instead of using plain variables (there were repeated variables' names between the first three lines and
the channels' lines, e.g., nshoots). Therefore, the active state of channel #3, for instance, is now head.ch(3).active instead of
head.active(3).
