gov.nih.mipav.model.file.FileGESigna5X

public class FileGESigna5X
extends FileBase

Reads both GE Neducak Systems MR 5X and LX. Modify to handle MRGE files from a GE signa-5 with IMGF starting at locating 3228 and image data starting at location 8424. Follows file format thru lenUsrDefData field; then varies from format.
