Hi, Dan Glad it worked and thanks for pointing out a more general mimetype - does any one else (other than me) want to vote to add <datatype extension="rda" type="galaxy.datatypes.binary:Binary mimetype="application/x-gzip" subclass="True" /> to datatypes_conf.xml.sample permanently ?

I do. This would be great as I am automating the creation of galaxy tools and I'd like to be able to enable this feature without requiring (either manual or programmatic) editing of datatypes_conf.xml. Note that serialized R objects also sometimes have the .RData extension -- both are valid -- so it would be good to support that as well. But now that I think about it, serialized objects are not always gzip files--depending on the value of the 'compression' flag used with the save() function, it may be gzip, bzip, xz, or even ascii! So maybe the mime type should be changed back to something different, like application/x-rlang-transport as you suggested. I tried this and it seemed to work; It did the filtering I wanted and I was still able to download a history item with this type. Dan Thanks, Dan

Hi, Dan. Using format="rda" will restrict the list to history items of the 'rda' datatype - but ONLY if the rda datatype has been defined! The easiest way to do that is to define a new datatype in datatypes_conf.xml and since rData is binary, you should subclass binary. Something like (untested - especially the mimetype !) <datatype extension="rda" type="galaxy.datatypes.binary:Binary" mimetype="application/x-rlang-transport" subclass="True" /> might work. A server restart is always required to load any new datatypes. Good luck!

It works! I changed the mime type to application/x-gzip, since serialized R objects are gzipped.

Thanks, Dan

Hi,

I have a tool wrapper with a <param> of type="data".

Currently, this renders as a text box with a drop down list that has 52 items in it (the number of things I have in my history, I guess).

I'd like to filter this list so that only some items in the history (in my case any item whose name ends with '.rda') are shown in this dropdown.

It seems like maybe the 'format' parameter to the 'param' tag is what I want, but: 1) I tried format="rda" and that didn't seem to change anything. 2) "rda" is not in the datatypes.conf file which the documentation suggests is required?

(.rda is an extension used for serialized R objects.)

The tool I'm working on only accepts rda files as input and the reason I'm asking for this is that it is all too easy to accidentally feed it a file of some other type. If the dropdown could be filtered so that only items which will work with the tool are shown, that would be great.

Is there a way to do that? Thanks, Dan ___________________________________________________________ Please keep all replies on the list by using "reply all" in your mail client. To manage your subscriptions to this and other Galaxy lists, please use the interface at:
