Introduction

Brain anatomy is inherently hierarchical - i.e. the brain consists of grey matter and white matter, grey matter consists of the cortex, cerebellum, and other squishy bits, etc. RMINC 1.5 adds the ability to work with these hierarchies of anatomy. The initial implementation is still a bit limited, with the definition of the hierarchies coming from the Allen Brain Institute.

The underlying representations of hierarchical anatomies in RMINC comes from the wonderful data.tree library. After the walk-through in this tutorial it’s worth going back to the data.tree documentation to expand your knowledge of what you can do with this representation.

Working within hierarchies

First, load the required libraries, as always.

library(data.tree)

Next, the data - again, nothing has changed from prior anatomical analyses so far - we load in the CSV file containing information about the scans in the study, and we also load in the label volume and its underlying average for visualization purposes (and it’s fine to either use the one resampled for your study or the original version).

# start with some data reading

gfAB <- read.csv("/hpf/largeprojects/MICe/lqiu/collaborator_40um/Scott_enrichment/Scott_groupA-B_jacobians.csv")


# add the blurred jacobians
gfAB$relative02 <- sub('.mnc', '_fwhm0.2.mnc', gfAB$relative)
gfAB$absolute02 <- sub('.mnc', '_fwhm0.2.mnc', gfAB$absolute)

# add some reorganization of the data
gfAB$treatment <- relevel(gfAB$treatment, ref="standard")
gfAB$genotype <- relevel(gfAB$genotype, ref="wt")
gfAB$sex <- gfAB$sex %>% recode('?' = "female")

# load the volumes
allvols <- anatGetAll(gfAB$labels, method="labels", defs="/hpf/largeprojects/MICe/tools/atlases/Dorr_2008_Steadman_2013_Ullmann_2013_Richards_2011_Qiu_2016_Egan_2015_40micron/mappings/DSURQE_40micron_R_mapping.csv", parallel=c("local", 7))
## Files 148,  are missing label right facial nerve (cranial nerve 7)
## Files 148,  are missing label left anterior lobule white matter
## Files 148,  are missing label right inferior olivary complex

# and read in the label and anatomical volumes
labelVol <- mincArray(mincGetVolume("/hpf/largeprojects/MICe/tools/atlases//Dorr_2008_Steadman_2013_Ullmann_2013_Richards_2011_Qiu_2016_Egan_2015_40micron/ex-vivo/DSURQE_40micron_labels.mnc"))
anatVol <- mincArray(mincGetVolume("/hpf/largeprojects/MICe/tools/atlases/Dorr_2008_Steadman_2013_Ullmann_2013_Richards_2011_Qiu_2016_Egan_2015_40micron/ex-vivo/DSURQE_40micron_average.mnc"))

Next it is time to make the defintions hierarchical. This will be identical for every study that uses this atlas, so there’s a good chance we will simply include the hierarchical definitions as data files in RMINC in the future.

For rolling your own, the CSV file is the same as it’s always been, except with an extra column giving the name of the corresponding structure in the Allen atlas. The allen.json file is obtained directly from the Allen institute, and contains their definition of anatomical hierarchies.

abijson <- "/hpf/largeprojects/MICe/tools/atlases/Allen_Brain/Allen_hierarchy_definitions.json"
defs <- "/hpf/largeprojects/MICe/tools/atlases/Dorr_2008_Steadman_2013_Ullmann_2013_Richards_2011_Qiu_2016_Egan_2015_40micron/mappings/DSURQE_40micron_R_mapping.csv"
hdefs <- makeMICeDefsHierachical(defs, abijson)
## Loading required package: rjson

With the hierarchies established, it’s time to add the volumes to hierarchical tree.

vols <- addVolumesToHierarchy(hdefs, allvols)

Let’s see what that looks like. vols is a data.tree object. Let’s print it:

# the limit=NULL bit prints the entire hierarchy, rather than stopping after a certain amount
print(vols, limit=NULL)

We can also directly access elements:

vols$meanVolume
## [1] 421.8789

And walk the hierarchy with $ indexing:

vols$`Basic cell groups and regions`$Cerebrum$`Cerebral cortex`$`Cortical plate`$`Hippocampal formation`$meanVolume
## [1] 39.25963

That is a bit tedious - the FindNode command can come to the rescue:

See how that just prints the subtree from the hippocampal formation onwards.

Let’s take a look:

hanatView(vols)
## Loading required package: visNetwork

The graph shown with the colours from the Allen atlas. Go ahead and use your mouse to zoom in.

And just the hippomcampus

hanatView(FindNode(vols, "Hippocampal formation"))

Let’s colour that by volume

hanatView(FindNode(vols, "Hippocampal formation"), "meanVolume", low=0, high=20)

And change the colour scheme:

hanatView(FindNode(vols, "Hippocampal formation"), "meanVolume", low=0, high=20, colourScale=topo.colors(255))

Trees can also easily be turned back into volumes - in this case it takes only the leaves. Let’s do that for the volumes:

volvol <- hanatToVolume(vols, labelVol, "meanVolume")
mincPlotSliceSeries(anatVol, volvol, low=0, high=10, begin=50, end=-50, legend="Volume")

This also works with subregions:

volvol <- hanatToVolume(FindNode(vols, "Hippocampal formation"), labelVol, "meanVolume")
mincPlotSliceSeries(anatVol, volvol, low=0, high=2, begin=150, end=-250, legend="Volume")

What about visualizing higher parts of the hierarchy? This is where pruning comes in - a word of caution, before we begin: pruning changes the underlying tree, so if you don’t want that clone it first and work on the clone:

# create a copy
volsCopy <- Clone(vols)
# keep the first four levels of the hierarchy
Prune(volsCopy, function(x) x$level < 4)
## [1] 574
# print it out
print(volsCopy, "meanVolume", limit=NULL)

Given that pruning takes a function, it can be much more complex too. Let’s only keep structures above 5mm in size, but do it in such a way that if any siblings are below 5mm, we keep none from that level onwards.

# notice the cloning again - leaves the initial vols intact
volsCopy <- Clone(vols)
# prune based on the criteria described above. The need to navigate is not to check on siblings that might have been pruned already
Prune(volsCopy, function(x) x$meanVolume > 5 & all(lapply(Navigate(vols$root, x$path[2:length(x$path)])$siblings, function(y)y$meanVolume)>5))
## [1] 559

# the Do function does something at every node in the hierarchy
vols$Do(function(x) {

  x$cov <- x$sd / x$meanVolume
})
# print it

Statistical analyses within hierarchies

How does one do stats on those volumes? Easy - there are hanat equivalents to all the usual, friendly functions

hVs <- hanatLm(~genotype, gfAB, vols)
## N: 260 P: 2
## Beginning vertex loop: 590 3
## Done with vertex loop
stats <- hanatToVolume(hVs, labelVol, "tvalue.genotypets")
mincPlotSliceSeries(anatVol, stats, low=2, high=5, symmetric=T, legend="t-stats", begin=50, end=-50)

hanatView(hVs, "tvalue.genotypets", low=2, high=5, symmetric=T)

And FDR? Works the same way:

hVs <- hanatFDR(hVs)
##

##   Computing threshold for  F-statistic 
##   Computing threshold for  tvalue-(Intercept) 
##   Computing threshold for  tvalue-genotypets

The main difference here is that rather than using the Benjamini & Hochberg (1995) method as is used for every other FDR invocation in RMINC, it uses the Benjamini and Yekutieli (2001) FDR algorithm, which is viable in the presence of dependence (as obviously exists in a hierarchy where higher level values are dependent on low levels).
