- <DATA>
-
- The SDF format is created from LINKSYS by using the "Export"
- option. If PEDRAW reads such a file in it treats it in the
- following way:
-
- 1. A new ID is created by concatenating the individuals family
- name with the LINKSYS ID to create a new unique name (meaning
- that information about several different pedigrees can be
- contained in the one SDF file). So individual 2-5 from pedigree
- F9 becomes F92-5.
-
- 2. Each of the (up to) ten phenotype codes is read into the ten
- text lines.
-
- 3.In a somewhat feeble attempt to guess diagnosis the program
- assumes that the first phenotype code refers to affection
- status. If it begins with a "2" or contains a "-2" (e.g. if the
- phenotype code is "1-2") then the PEDRAW diagnosis code is set
- to 1 (for solid shading). Otherwise it is set to 0. If this does
- not end up right the diagnosis codes can be adjusted
- subsequently by hand <ADJUST> <DATADAT -patterns>.
