Hola a todos, me gustaría realizar una consulta asociada a la generación de valores genéticos del pedigreemm en R. Primero generé el archivo de pedigree incluyendo los parentales para posteriormente estimar la varianza aditiva y los valores genéticos para cada individuo, relacionando los individuos por medio de la matriz de parentesco. Me da todo perfecto, el complemento pedigreemm trabaja muy

I want to implement a unique category tree per user in my system, and I was hoping to use "acts_as_tree" on my category model. It seems as if acts_as_tree makes the assumption that the entire table the model is off of is one large tree. I actually want each user to have their own category trees all stored in the category table so I need it to scope off of the user_id.

...optional parameter to the method could specify the id of an entry point to traverse from, to allow only part of the tree to be traversed. The default argument would be the root id. Example: # set all labels to upper case my_tree.traverse(some_id) do | item_id | new_label = my_tree.get_item_text(tree_id).upcase my_tree.set_item_text(tree_id, new_label) end ---------------------------------------------------------------------- You can respond by visiting: http://rubyforge.org/tracker/?func=detail&atid=221&aid=6826&group_id=35

Hello, I have a tree structure that needs to be converted into a nested set. A great deal of work has already been done on the tree items, so maintaining the integrity of the id''s is mandatory. However I need the ability to access entire branches of the tree, which is what Nested set does. Does anyone have any suggestions on how to efficiently transfer the tree to the nested set and

From: Anand <anand.jain@oracle.com> This patch adds creation-time to the snapshot list display, which would help user to better manage the snapshots when number of snapshots grow substantially.

Hello, This is the userspace part of restriper, rebased onto the new progs infrastructure. Restriper commands are located under ''balance'' prefix, which is now the top level command group. However to not confuse existing users ''balance'' prefix is also available under ''filesystem'': btrfs [filesystem] balance start btrfs [filesystem] balance

This is the next patch series for scrub userland tools. Change log v1->v2: - commands now reachable as "btrfs scrub ..." instead of "btrfs filesystem scrub ..." - ability to scrub a single device instead of a whole file system - superfluous command line options removed - resume is now a separate command ("scrub resume") instead of "scrub start -r" -
