As you indicated chimera does read the dsn6 format. It does not recognize the extension .dsn6 (the one given in the PDB files) but in the Open->Type selection dialogue there is the option 'BRIX or DSN6 density map' that works.

Hi Hernando,<br>
Chimera does not convert MTZ to density maps, sorry, as discussed in various older posts.<br>

I don't really understand the part about dsn6: that is already a density map format, so if you have that, you could try opening it as dsn6 (e.g. by using filename ending with .omap or .brix).<br>

<br>
ChimeraX can read mtz files if you both:<br>
(1) already have an atomic structure that goes with the mtz<br>
(2) download and install the Clipper bundle from the ChimeraX Tool Shed<br>
(start ChimeraX, then use menu Tools... More Tools to get to the Tool Shed)<br>
<br>
More details on opening MTZ in ChimeraX:<br>
