Dear Chaitanya,<div><br></div><div> thanks a lot for your response. As you pointed out the metadata tag was misspelled. Correcting it fixed the first problem. However I still have the second problem The inspection of <font class="Apple-style-span" face="'courier new', monospace">Ig</font> with the debugger shows non consistent values for the member variables of the GDALDataset class (see a snapshot at the bottom of the email). You suggest that there may be a bug with the debugger, but I doubt this is the case. In fact if I continue with the execution of the code, the instruction:</div>
<div><br></div><div><span class="Apple-style-span" style="font-family: 'courier new', monospace; ">[...]</span></div><div><span class="Apple-style-span" style="font-family: 'courier new', monospace; ">GDALRasterBand *poBand = Ig->GetRasterBand( b );</span></div>
<div><span class="Apple-style-span" style="font-family: 'courier new', monospace; ">[...]</span></div><div><font class="Apple-style-span" face="'courier new', monospace"><br></font></div><div><font class="Apple-style-span" face="'courier new', monospace"><span class="Apple-style-span" style="font-family: arial; ">returns a NULL pointer when b is zero, and this seems to be consistent with the fact that the debugger says that </span>Ig<span class="Apple-style-span" style="font-family: arial; "> is composed of 0 bands (nBands = 0). I would appreciate if you or anybody else have some suggestion to understand and solve this problem.</span></font></div>

2. The driver did report the error message correctly after processing the creation options. There may be a bug with the debugger.<br>
