ARB_NT/Species|Genes|Experiments/Info/FIELDS/Show all hidden fields
ARB_NT/Species|Genes|Experiments/Info/FIELDS/Scan unknown fields
ARB_NT/Species|Genes|Experiments/Info/FIELDS/Remove unused fields
DESCRIPTION
Each function scans the database to detect all existing fields.
'Show all hidden fields' unhides all currently hidden fields.
'Scan unknown fields' scans the database for fields that are not listed
in the field list and adds them to that list.
'Remove unused fields' deletes all fields from the field-list which are
not used anywhere in the database.
NOTES
Normally it is not necessary to run 'Scan unknown fields' unless
some external programs generate new and yet unknown fields
or if the ARB programmers forgot to announce a field as known.
In the latter case please write to devel@arb-home.de and describe which
fields was created by doing what.
