We are using MRtrix for many different things in our tractography pipelines. At the moment, we are struggling a lot with DICOM data from Philips scanners. We are trying to use mrinfo to get gradient directions from the data, which works very consistently in general with other vendors, but with Philips it cannot seem to find the gradient information.
When we look manually through the DICOM headers, we also cannot find the gradient information. We are wondering if there are alternative reconstruction files we are missing from the data which are needed (we have read somewhere about .par and .rec files from Philips scanners)
We wonder if anyone in the MRtrix community has experience with DWI on Philips machines and can advise on how to track down the gradient information (we receive the data from many different MRI sites, so if we need extra files we need to make sure they send them in the future)
