molconvert structure to image - but only the first structure

Hi,

is there a way to tell the molconverter to only produce an image from specific structures of a file? I only need e.g. the 1st image of the structure file.

If you convert an SD file that includes several record into image format with molconvert, only the first record will be processed.

molconvert jpeg moremols.sdf -o first.jpeg

but is it reading the whole file first? because i'm using this as a thumbnailer in my gnome desktop environment and it takes ages for big sd files.

I recommend to write a simple batch script that cuts the first record from the SD file and feed molconvert with its output.

There is another solution too. With the MolImporter API you can write your own application where you can control import/export more flexible.

Please see the SimpleConverter example in the Marvin Beans package (examples/beans/converter) it converts the first record of a structure file into the given format.

thank you very much
