This section describes the columns that can be displayed in the main record table.

Not all these columns are necessarily displayed; you can configure what is actually shown - see Customization.

For details on how to use the main table, including sorting, filtering and tagging, see Main Window.

The main table columns can be classified into 2 groups: those that are computed by analyzing the pedigree of each animal, and those that are not.

Columns That Do Not Require Pedigree Analysis

This includes all the main columns containing basic facts about each animal, such as name/ID, sex, parents, and so on.

Column Symbol (if any) Description
Record Name

Name of this animal, if it has one distinct from its ID.

ID

The input ID of this animal, if it has one that is distinct from its name.

Seq#

The input sequence number. This is always equal to the order in which the records were read in from the input file, with the first record given sequence number 1.

This may or may not be the same as the ID or Rec#, depending on the order in which records are presented in the input data, and how your input IDs are assigned.

Rec#

The internal PedScope-assigned record number of this animal. This is not the same thing as the record name or ID as given in the input data, nor is it the same as the input sequence number.

During the importing of data, PedScope has to renumber (reorder) the input records to ensure that they are in an order that guarantees that parents always precede their offspring. This ordering is required to implement certain algorithms quickly, and also enables PedScope to discover any self-parenting errors during input (a self-parenting error being when an animal appears to be descended from itself, which can happen when there are errors in the input data).

See also the 'Age If Living' column (below).

Sire

Name or ID of the sire of this animal.

Dam

Name or ID of the dam of this animal.

Sex

The gender of this animal. Normally displayed as M or F (though you can change this: see Customization).

It will be shown in a faded color if the sex has been deduced on input; this happens when the sex is not stated in the input data but has been deduced from the animal's appearance as the sire/dam of other animals.

Living*

Whether or not this animal is considered to be alive. This is determined from a combination of other information.

Firstly, if the imported data has a 'Dead' or 'Alive' column value (see Importing Data), then this defines whether or not the 'Living' column is true. Failing that, if the date of death is known the 'Living' column is set to false. Otherwise, if the date of birth is known and the current age of the animal exceeds a user-chosen threshold, then again the 'Living' column is set to false. Finally, in the absence of any other way to determine the living status, it is set to a user-chosen default. See Customization.

Date of Birth DOB

Date of birth of this animal or litter.

Date of Death DOD

Date of death of this animal.

#Offspring

No. of immediate descendants of this animal (i.e., the number of other animals for which this animal is either the sire or dam).

#Males

No. of immediate descendants of this animal that are male.

#Females

No. of immediate descendants of this animal that are female.

#Unknown sex

No. of immediate descendants of this animal whose sex is not known.

#Families

No. of family records in which this animal is a parent.

#Litters

No. of litter records in which this animal is a parent.

#Full Siblings

No. of other animals with the same sire and dam as this animal. If either sire or dam is not known this is always 0.

#Litter Siblings

No. of other animals with the same sire and dam and date of birth as this animal. If either sire or dam is not known this is always 0.

#Half Siblings

No. of other animals that have either the same sire, or the same dam, as this animal, but not both. If either sire or dam is not known this is always 0.

#Paternal Siblings

No. of other animals with the same sire as this animal. If the sire is not known this is always 0.

#Maternal Siblings

No. of other animals with the same dam as this animal. If the dam is not known this is always 0.

#Siblings

No. of other animals with either the same sire, or the same dam, as this animal, or both.

Generation Number
(1 + Parental Max)
GN

The generation number of this animal, defined as 1 plus the maximum of the sire and dam generation numbers. Founders always have GN 0.

Generation Number
(1 + Parental Avg)
GN

The generation number of this animal, defined as 1 plus the average of the sire and dam generation numbers. Founders always have GN 0.

Age at Death

The time period between the date of birth and date of death of this animal.

Age If Living*

The current age of this animal, but only if it is considered as being alive (see 'Living' column).

Age At First Offspring

The time period between this animal's date of birth and that of its first known offspring.

Age At Last Offspring

The time period between this animal's date of birth and that of its last known offspring.

Generational Age

The average of the time period between this animal's date of birth and the dates of birth of its parents. Requires that 3 dates of birth to be known.

Age Of Sire At Birth

The time period between this animal's date of birth and that of its sire.

Age Of Dam At Birth

The time period between this animal's date of birth and that of its dam.

* Living and Age If Living: These columns primarily exist to provide a way for large data sets to be sorted so as to bring all animals with a given current age, or all animals known to be living, together in the main record table. This makes it easier to tag the 'current' population (i.e., those that are alive), using a range-tagging operation. You may well want to do this if you are using PedScope to make mating recommendations.

Columns Computed By Pedigree Analysis

These are columns whose values can be computed by analyzing the pedigree of each animal at the same time as the inbreeding coefficient is computed.

The depth of ancestry (i.e., the number of generations) used in this analysis is a configurable parameter: the Inbreeding #generations setting on the General tab of the Document Settings window (File|Document Settings). You can either set a specific depth limit, such as 8 generations, or you can instruct PedScope to include all available ancestry by setting it to zero.

It may seem surprising but if you have a very large data set with many generations of ancestors present, PedScope will normally calculate these metrics much more quickly if you direct it to include all known ancestry. This is because of algorithmic optimizations that are used when analyzing the entire pedigree in a single step (rather than having to identify a separate sub-pedigree for each animal).

Columns Symbol (if any) Description
Inbreeding Coefficient F

Wright's inbreeding coefficient for this animal, computed to the chosen depth of ancestry (see above).

Ancestral Inbreeding Coefficient

The ancestral inbreeding coefficient computed using the direct method of Ballou.

This column is optional. To disable it choose File|Document Settings, click onto the Compute tab, then uncheck the Compute ancestral inbreeding coefficients option.

#Generations Seen
#Generations Full
#Ancestors
#Ancestors Unique
Completeness
#G Seen
#G Full
#A
#A Unique

These are various metrics about the ancestors found when analyzing the pedigree of this animal. These are optional - to disable them choose File|Document Settings, click onto the Compute tab, then uncheck the Compute individual pedigree metrics option.

#Generations Seen is the maximum depth of ancestry (#generations) seen.

#Generations Full is the number of generations of ancestors that were full (no holes).

#Ancestors is the total number of occurrences of ancestors seen. Ancestors occurring multiple times will add 1 to this value for every occurrence.

#Ancestors Unique is the number of distinct ancestors seen.

Completeness is the proportion of the pedigree that was full (no holes).
