Subject area	Neuroscience
More specific subject area	Diffusion weighted imaging and tractography
Type of data	Figure, table
How data was acquired	Diffusion-weighted MR images were acquired on a SIEMENS MR tomograph from human participants
Data format	Analyzed
Experimental factors	Type of head-coil (12-channel vs. 32-channel coil), number of reconstruction repetitions (1 vs 10 repetitions), streamline selection variant (defining fuzzy versus no fuzzy borders of the seed mask; selecting streamlines that end in versus that visit a seed)
Experimental features	Participants were scanned twice within one week and tractography was performed in two independent tracking runs for both testing sessions using both types of head-coil. Whole-brain fiber reconstruction was carried out once with 1 repetition and once with 10 repetitions. Streamlines for connections between the seeds of the AAL atlas were selected using four different streamline selection variants (endpoint_nofuzzy; endpoint_fuzzy; visiting_nofuzzy; visiting_fuzzy).
