MRIcloudT1volumetrics

MRIcloudT1volumetrics is an R package for working with the output of MRIcloud T1 volumetric data. As of this writing, the package has three purposes:

It text parses and reads in data from the most popular T1 processing algorithms through the function readSubject
It can convert that data into a dataframe.
It can read in a series of files and concatentate them into a dataframe

Here’s an example of basic reading in of one subject.

library(MRIcloudT1volumetrics)
fileLoc = system.file("extdata", "kirby127a_3_1_ax_283Labels_M2_corrected_stats.txt",
 package="MRIcloudT1volumetrics")
test = readSubject(fileLoc)
length(test)
