We will only be covering a few basic DataLad functions to get and drop data. As these datasets are large, this will allow you to only work with the data that you need for a specific tutorial and you can drop the rest when you are done with it.Īll of the DataLad commands can be run within Python using the datalad python api. Specific files can be easily downloaded using datalad get, and files can be removed from your computer at any time using datalad drop.
GIT ANNEX DROPBOX DOWNLOAD
This allows you to explore all of the files in the dataset, without having to download the entire dataset at once.
GIT ANNEX DROPBOX INSTALL
While DataLad offers a number of useful features for working with datasets, there are three in particular that we think make it worth the effort to install for this course.Ĭloning a DataLad Repository can be completed with a single line of code datalad clone and provides the full directory structure in the form of symbolic links. It provides a handy command line interface for downloading data, tracking changes, and sharing it with others. The easist way to access the data is using DataLad, which is an open source version control system for data built on top of git-annex. If you are taking the Psych60 course at Dartmouth, we have already made the data available on the jupyterhub server. Note, that the entire dataset is fairly large (~42gb), but the tutorials will mostly only be working with a small portion of the data (5.8gb), so there is no need to download the entire thing.
GIT ANNEX DROPBOX HOW TO
In this notebook, we will walk through how to access the datset using DataLad. Though the data is being shared on the OSF website, we recommend downloading it from our g-node repository as we have fixed a few issues with BIDS formatting and have also performed preprocessing using fmriprep. There are a total of 94 subjects available, but we will primarily only be working with a smaller subset of about 15. This dataset is well suited for these tutorials as it is (a) publicly available to anyone in the world, (b) relatively small (only about 5min), and (c) provides many options to create different types of contrasts. Read the original paper for more specific details about the task and the dataset paper. There are 100 trials in total over a 5-minute scanning session. The trials are randomized across conditions and have been optimized to maximize efficiency for a rapid event related design. Several of the tasks are cued by reading text on the screen (i.e., visual modality) and also by hearing auditory instructions (i.e., auditory modality). The Pinel Localizer task was designed to probe several different types of basic cognitive processes, such as visual perception, finger tapping, language, and math. There are in total just short of 200 000 files.Many of the imaging tutorials throughout this course will use open data from the Pinel Localizer task.
GIT ANNEX DROPBOX PDF
The largest files are about 400 MB is size, most of the content are images, music, pdf and other binary files. My Dropbox folder is about 32 GB in size. Set-alias git 'C:\Program Files\Git\bin\git.exe' Robocopy D:\Dropbox "F:\Dropbox backup\Dropbox" /MIR /Z /NJH /ndl /nc /ns Register-ScheduledJob -Name GitBackup -Trigger $trigger -ScriptBlock ` The way I do this is by creating a ScheduledJob in PowerShell (using Windows), that looks like this: $trigger = New-JobTrigger -Daily -At "5am" So, having just learned Git, being completely in love, and just mad with power, I decided to backup dropbox with Git. While it's probably not gonna be the end of all, I realized that I don't have a (recent) backup of my Dropbox contents. And how I'm screwed if they manage to infect just one of my computers, and given enough time to synch the encrypted files to dropbox. So last night I was reading about all these ransomware stuff that flourish on the web, that encrypt all your files and demand a ransom to decrypt them. So I've been learning Git this last few months after our company migrated from SVN to Git, and I'm just loving it.
