============================================= How to use the Connectome File Format Library ============================================= .. note:: Example connectome files are provided in the GitHub repository `cffdata `_. Import the library. Subsequently, we assume that this has been done:: from cfflib import * Load the dataset from the file system:: a=load_from_meta_cml('example_dataset_01/meta.cml') You can print all the loaded connectome objects:: print a.get_all() If you have a zipped file with ending .cff, you can load it as well with:: a=load_from_cff('datasets/ds1/connectomefile.cff') You can get the first network and load it like this:: mynetwork = a.get_by_name('Network Lausanne83')[0] mynetwork.load() The loaded network object accessible through the data attribute (a NetworkX object):: print mynetwork.data You see that it is a NetworkX graph. You can modify it as you like. After modification, you can store it, which stores it in the corresponding file that this CNetwork was referenced to (relative path):: print mynetwork.src mynetwork.save() Show other attributes:: print mynetwork.name print mynetwork.dtype print mynetwork.description To show the metadata attributes as dictionary:: print mynetwork.get_metadata_as_dict() You can save the currently loaded connectome file:: save_to_cff('myconnectome.cff', a) The same you can do for other connectome objects, if the corresponding Python libraries are installed correctly:: # CVolume obj = a.get_by_name('Example Volume') obj.load() print obj.data # CSurface obj = a.get_by_name('Example Surface') obj.load() print obj.data # CTrack obj = a.get_by_name('Tractography') obj.load() # You do not want to display all fibers, just show the header print obj.data[1] # CTimeseries obj = a.get_by_name('Generated timeseries data') obj.load() print obj.data # CData obj = a.get_by_name('Arbitrary data file') obj.load() print obj.data # CScript obj = a.get_by_name('Analysis Script MMXXXIV') obj.load() print obj.data # CImagestack obj = a.get_by_name('FIB Rat Striatum') obj.load() print obj.data
