[Gate-users] Regarding ASCII SINGLES OUTPUT

[open researcher]

Thank you for the correction,  I didn't notice the line 'For the next
sections, the system will be set as a cylindricalPET system, so that the
number of lines concerning the Volume ID of each level will always be 5' in
users guide so I got confused.
