The process has been running for almost one hour now and is using upwards of 16 GB of memory. I've run IDFileConverter with \"-debug 10\" in the hope of some diagnostic output, but all I got were these messages early on:\r\n> Converting from mzid: you might experience loss of information depending on the capabilities of the target format.\r\n> No retention time found for 'SpectrumIdentificationResult'\r\n\r\nDoes anyone have an explanation for why this conversion would use so much memory (and take so long)?"}}
