Function Documentation

int anaExists (  char *  dbname  )

Check if Analyze files exist. Returns 0, if they do not, 1 if .img and .hdr do exist, and 2, if also .sif exists.

int anaFlipping (   )

Check whether Analyze image is flipped in z-direction when it is read from/written to file (x,y-flipping is done always)

int anaPrintHeader (  ANALYZE_DSR *  h, FILE *  fp )

Print the contents of Analyze header to specified file pointer. Returns: Returns 0 if ok.

int anaReadHeader (  char *  filename, ANALYZE_DSR *  h )

Read analyze header contents. Returns 0, if ok. Parameters: filename  Name of file to read (including path and extension) h  Pointer to previously allocated header structure

int anaReadImagedata (  FILE *  fp, ANALYZE_DSR *  h, int  frame, float *  data )

Read Analyze 7.5 image data, convert byte order if necessary, and scale values to floats. Reads only one frame at a time! Parameters: fp  File opened previously in binary mode h  Header read previously frame  Frame number to read data  Pointer to image float data allocated previously

int anaWriteHeader (  char *  filename, ANALYZE_DSR *  h )

Write analyze header contents. header field 'little' is used to determine the required byte order. Returns 0, if ok. Parameters: filename  Name of file to read (including path and extension) h  Pointer to Analyze header structure
