Hey there,
now I have another problem with selectionmode. I have 3 conditions (resMas, kitsch and nonresMas)  and in each condition I have a different amout of variables. 
Now I want to show all images of each condition just once and they should be selected randomly. I have tried it with /select = noreplace in the picture-Item and sequence in the block element as you can see in the code. I think the pictures are selected randomly BUT the picture of the kitsch and resMas-condition are shown multiple times.

You need to sample your *<trial>* elements in the desired proportions.

/ trials = [1-12 = noreplace(a, b, c)]

samples a, b and c in *equal* proportions, i.e. there'd be 4 a-trials, 4 b-trials, and 4 c-trials in random order.

If you wanted 6 a-trials, and only 3 b-trials and 3 c-trials, you would have to define

/ trials = [1-12 = noreplace(a, a, b, c)]

You need to apply the same reasoning to your case, i.e. you ought to define a noreplace() pool containing 15 x resMas, 1 x nonresMas, and 1 x kitsch.

Thanks for your help! But then the trials are not mixed like on picture from the trial resMas, than one picture form the trial nonresMas and than one ´picture from the trial resMas again....

Just tried it, works perfectly, also the randomisation! Thanks!

Just one another question: How can I now store the sequence in which the pictures are shown in a variable. This is important, because I later need to know when which picture was presented and which rating / brain activity belongs to which picture...

You have a full record of the sequence in the data file. You can either use that, or you can set up a <values> entry, concat the current item /ontrialend and log that value to the data file.
