You can see the creation, resize, and final memory-mapping operations being reported here. Mrconvert: image 'test.mif' initialised with strides =, start = 10815, using indirect IO Mrconvert: file 'test.mif' mapped at 0x7f1ecedba000, size 195077376 (read-write) Mrconvert: memory-mapping file 'test.mif'.

Mrconvert: resizing file 'test.mif' to 195085088 Mrconvert: creating empty file 'test.mif' You should see this output for a standard mrconvert run: $ mrconvert in.mif test.mif If you run with the -debug option, we should be able to figure out which step is failing. My money was on the final memory-mapping stage (it’s possible that the particular file-system you’re using doesn’t support memory mapping, for instance). There’s a few steps that take place one after the other, and one of them might be failing. It’s possible that the initial file creation step succeeds, but the resize step (which allocates storage for the raw image data over and above the size of the header) fails.
