unknown.mrc in exported stacks

hi again,  

am still struggling with getting an exported stack containing original micrograph names.  From what I understand (in first post below) this information may be lost forever during import?  I hope that adding in this meta data for future cisTEM iterations will be considered as the default when exporting stacks.

I followed this post, which gave me particle number, but I instead want micrograph name.

I tried following this post under subsection "images in a group" but received null return when I input "select * from image_group_list;"

thanks again for your hard work
