Hi Robert,<div><br></div><div>I was able to open the same file in ImageJ using the following parameters:</div><div><br></div><div>Image Type: 32-bit Real</div><div>Width: 64 pixels</div><div>Height: 64 pixels</div><div>Number of images: 64</div>
<div>Little-Endian Byte Order</div><div><br></div><div>I don't know why RawImageIO is saying that there is just 16384 bytes,</div><div><br></div><div>Thanks & Regards,</div><div>Luis</div><meta charset="utf-8"><div>

Your image parameters yield an expected file size larger than that of the file you are trying to read, i.e., 64*64*64*32/8 = 1048576 bytes when your file is only 16384 bytes.<br><br><div class="gmail_quote"><div><div></div>
