|
In this video, I will present you
|
|
|
|
00:02.600 --> 00:05.500
|
|
the shinny application scMonitor, which is
|
|
|
|
00:05.500 --> 00:08.200
|
|
oriented to easily explore
|
|
|
|
00:08.200 --> 00:10.300
|
|
a previously processed seurat object.
|
|
|
|
00:11.600 --> 00:13.800
|
|
Firstly, you should select the file
|
|
|
|
00:13.800 --> 00:16.800
|
|
containing the seurat object.
|
|
|
|
00:16.800 --> 00:19.000
|
|
For now, the file format must be RDS.
|
|
|
|
00:19.700 --> 00:21.600
|
|
Depending on the object size and
|
|
|
|
00:21.600 --> 00:23.800
|
|
computer potency the loading
|
|
|
|
00:23.800 --> 00:25.000
|
|
will take more or less time.
|
|
|
|
00:26.200 --> 00:28.200
|
|
UMAP distribution that generates
|
|
|
|
00:28.400 --> 00:30.000
|
|
is the same that shows as default,
|
|
|
|
00:30.400 --> 00:33.400
|
|
usually clusters identified by seurat itself.
|
|
|
|
00:33.400 --> 00:37.200
|
|
We can group colors by any
|
|
|
|
00:37.200 --> 00:39.300
|
|
other variable that we have included in the
|
|
|
|
00:39.300 --> 00:42.600
|
|
metadata from the object specifying it in "GroupBy".
|
|
|
|
00:43.200 --> 00:45.500
|
|
Tipically, the sample origin or
|
|
|
|
00:45.500 --> 00:46.300
|
|
a manual annotation
|
|
|
|
00:46.300 --> 00:47.700
|
|
from the cell type.
|
|
|
|
00:48.800 --> 00:51.400
|
|
Distribution can also be divided by
|
|
|
|
00:51.400 --> 00:54.500
|
|
another variable selecting in "FacetBy".
|
|
|
|
00:54.500 --> 00:57.300
|
|
In this case, we are looking at
|
|
|
|
00:57.300 --> 00:59.900
|
|
the distribution of cell type
|
|
|
|
00:59.900 --> 01:01.000
|
|
by the sample origin.
|
|
|
|
01:02.800 --> 01:05.800
|
|
Another available visualization is to show expression
|
|
|
|
01:05.800 --> 01:08.100
|
|
for a group of genes separated by a white space
|
|
|
|
01:08.100 --> 01:10.400
|
|
over UMAP distribution.
|
|
|
|
01:11.300 --> 01:13.500
|
|
With the "Height" bar we can adjust
|
|
|
|
01:13.500 --> 01:15.500
|
|
the size in order to feel comfortable.
|
|
|
|
01:18.900 --> 01:22.700
|
|
Finally, we can create signatures in order to visualize
|
|
|
|
01:22.800 --> 01:25.200
|
|
their score from cells.
|
|
|
|
01:25.200 --> 01:27.300
|
|
One must indicate the signature name and
|
|
|
|
01:27.300 --> 01:29.800
|
|
on the box below specify the genes
|
|
|
|
01:29.800 --> 01:32.600
|
|
that are included. Once added, you can
|
|
|
|
01:32.600 --> 01:34.700
|
|
specify its name in the
|
|
|
|
01:34.700 --> 01:35.500
|
|
signatures box.
