ORBIT-USER: About imageNodes for 100+ nodes

[Nanyan Jiang]

Hi Sachin,

    Thanks. I tried to use the short cut you mentioned. It 
worked yesterday. 
However, this morning when I wanted to imageNodes it seemed not working 
for single node image or multiple node images. Here are experiment IDs. 
What I used were

    imageNodes [10,11] file.ndz
    imageNodes [10..16,10..16] file.ndz

    Experiment ID: grid_2006_09_27_08_42_43
    Experiment ID: grid_2006_09_27_08_42_34

When I used
    imageNodes [9,16] file.ndz
    imageNodes [11..13,11..13] file.ndz
They are ok!

The experiments were successful again. Are there any particular nodes, 
which should not be included in the image node group (I guess node 
[10,11] should be excluded)? Or are there any other issues to 
be aware when imaging the nodes? Thanks.

Best,

Nanyan
