Dear MRtrix community,
I recently updated the MRtrix software on our server (it turned out we were on a 2019 version), and I am now experiencing an issue/change in the output of .csv files using tcksample.
I used to get a .csv file which just contained the number of mean FA values per streamline, but now the first row contains the command history, and the second row the output values. I use R to gather all the values from the .csv files into one large data frame to perform statistics, but now I have difficulties isolating the numerical values to do calculations with when I read the .csv file in R. I could not figure out from the tcksample documentation if there is a way to not include the command history in the .csv file.
So my question is: how do I output .csv files from tcksample without the command history in the first row?
