I require help to perform peptide mass-fingerprinting from 50 protein spots (excised from 2d gel and trypsinised thereafter)

1. I have MALDI-TOF/ MS data for secretome proteins from B. anthracis and B. cereus

2. I cannot use MASCOT fingerprint search as it DO NOT have B. anthracisproteome databse

3. i want either licensed version of MASCOT software (I don't have funds to buy the same)

4. I have to create a custom database of B. anthracis and B. cereus proteomes

5. I have to use my data against this custom database to perform peptide mass fingerprinting to identify unknown proteins.

6. please help
