Hi Kostas,

I tghink generally 300 dpi is sufficient for publication but you can ray trace to any sort of resolution and then down size your graphic. See posts on High end graphics but this should help

*To get 4in by 4in figure @600dpi

ray 2400, 2400*

*
*

*Then png picture.png

Then resize in something like photoshop...increase resolution to that desired 
and reduce image size so file size is similar to original

Hope this helps

J*

Dear PyMolers

I am about to write a paper and I want your suggestions for the pictures I am going to make. First of all I will use white background and the structure is a NMR one. So I need to display the backbone of the ensemble and the rest pictureswill be cartoons and sticks mainly. I want to achieve nice quality pictures (resolution, depth etc.) that's why I am asking for your experience on this issue.
Any hints for the ray parameters it will be appreciated.
thanks in advance kostas

PS: virtually no memory space limitations for any action it is to perform
