As of February 22, authors submitting to MCP are no longer required to place their RAW data in a publicly accessible database. I don't know why the journal has made this decision, but I don't like it. Its simply too easy in this field to fabricate data. MCP still 'strongly encourages' the deposition of data, but I would prefer that it was mandatory unless particular stipulating conditions, such as patent rights were involved. Even in those cases I feel that the data should be deposited once those stipulations have expired or been resolved.
