it looks like someone accidentally turn on jpeg compression on the console. Our converter does not read jpeg. You can use dcmdjpeg from the dcmtk toolkit to create new dicoms that are uncompressed, something like
dcmdjpeg +te old.dcm new.dcm

I am trying to import an MPRAGE structural sequence of 160 images acquired from a Siemens Allegro. Only one of my subjects displays the following error message when I try to import him using the "recon-all -s Subject -i" function. Below is the brief error message and full log. Thanks in advance for any assistance.
