Individual Site Subject IDs

Each project initiated at CIVM, and each specimen processed here, is assigned
a unique (within CIVM) identifier. These identifiers are used throughout CIVM's
workflows and data dissemination. For collaboration with other labs,
we can associate an "foreign specimen ID" with each specimen; this
identifier is a string (0-40 characters), and we impose no other
constraints on its structure or content. We have not previously needed
external project identifiers, but we are prepared to add such a field
to our project database.
Project Identifiers
CIVM project codes are strings of the form
yy.name.dd, where
yy is the
last two digits of the year the project was initiated,
name is the
investigator surname (for external investigators) or initials (for CIVM
investigators), and
dd is a two-digit sequence number distinguishing
multiple projects with the same investigator. We currently limit
project codes to 30 characters.
Examples:
We initiated our first study with Mark Ellisman in 2002. The project code
for this study is
02.ellisman.01.
Alex Badea initiated her first project as part of the CIVM team in 2004. Its
project code is
04.abb.01. She initiated a second project in 2005; its
project code is
05.abb.02.
Specimen Identifiers
CIVM specimen IDs are strings of the form
yymmdd-n:s, where
yymmdd is
the date (2-digit year, 2-digit month, 2-digit day of month) we prepare
the specimen for imaging,
n is a number starting at 1 and incremented
for each specimen prepared on a given day, and
s is a subspecimen
number incremented for each subspecimen prepared from an original
specimen. By convention, whole animals and phantoms are given a
subspecimen number of 0, while "disembodied" specimens (animal parts we
received without processing the original animal) are given a
subspecimen number of 1. We currently limit specimen IDs to 16
characters, which can accomodate thousands of specimens per day and
thousands of subspecimens per specimen.
Examples:
On June 26, 2006, we processed three animals. The first received a
specimen ID of
060626-1:0. The second received an ID of
060626-2:0.
The third received a specimen ID of
060626-3:0. This third animal's
head was isolated for imaging; the head received an ID of
060626-3:1.
(If we'd gone on to remove the brain from the head, the brain would
have received an ID of
060626-3:2.)
On June 15, 2006, we processed a pregnant animal to do fetal images.
The parent animal received an ID of
060615-1:0. Each fetus received
its own ID as a subspecimen of the parent, starting with
060615-1:1 and
ending with
060615-1:12.
On April 13, 2006, we processed sixteen animals. The first received an
ID of
060413-1:0; the last,
060413-16:0.
