Mascot
| IMPORTANT |
The error tolerant search in Mascot 2.2.06 and earlier has a limit of 1024 modifications.
The number of specificities in Unimod has recently exceeded this limit.
Mascot 2.3: No action necessary
Mascot 2.2: Ensure you update to 2.2.07 before downloading the latest unimod.xml.
Mascot 2.1 and earlier: The total number of the entries in mod_file and substitutions must
not exceed 1024. After downloading mod_file, open it in a text editor
and delete entries that are not of interest. Alternatively, delete entries from subsitutions,
or some from each file. You cannot have an empty substitutions file, but
it can be reduced to a single entry.

2.1 and earlier.
Archived mod_file for Mascot
2.1 and earlier. This is the last mod_file generated from the original Unimod database,
before the switch to PSI-MS approved names, (11 Nov 2006).
Note: In unimod.xml, there is a flag called hidden at the specificity
level. Modifications with hidden="1" are only displayed by Mascot when the checkbox
for Display all modifications is checked. Otherwise, you see a shorter list of common
modifications (hidden="0"). Some 3rd party
software is not aware of this switch, and only ever displays the short list of common modifications.
The work-around is to change the hidden flag so that all modifications are treated as common. To do
this, use the search and replace function of any text editor to replace all instances of
hidden="1" with hidden="0". If you use a word processor, make
sure the file is saved as a plain text file.
