Background: A variety of neuroimaging software packages have been released from various laboratories\r\nworldwide, and many researchers use these packages in combination. Though most of these software packages\r\nare freely available, some people find them difficult to install and configure because they are mostly based on\r\nUNIX-like operating systems. We developed a live USB-bootable Linux package named ââ?¬Å?Lin4Neuro.ââ?¬Â This system\r\nincludes popular neuroimaging analysis tools. The user interface is customized so that even Windows users can use\r\nit intuitively.\r\nResults: The boot time of this system was only around 40 seconds. We performed a benchmark test of\r\ninhomogeneity correction on 10 subjects of three-dimensional T1-weighted MRI scans. The processing speed of\r\nUSB-booted Lin4Neuro was as fast as that of the package installed on the hard disk drive. We also installed\r\nLin4Neuro on a virtualization software package that emulates the Linux environment on a Windows-based\r\noperation system. Although the processing speed was slower than that under other conditions, it remained\r\ncomparable.\r\nConclusions: With Lin4Neuro in oneââ?¬â?¢s hand, one can access neuroimaging software packages easily, and\r\nimmediately focus on analyzing data. Lin4Neuro can be a good primer for beginners of neuroimaging analysis or\r\nstudents who are interested in neuroimaging analysis. It also provides a practical means of sharing analysis\r\nenvironments across sites.
