Conversion from plink to merlin failes with Mega2

Question

[Arija]

Hi,

I am trying to covert a dataset from plink to merlin format using mega2

Parameters are:

Input_Pedigree_File=clean-Z-chr8.hapmap-snps.pruned.fam
Input_Map_File=clean-Z-chr8.hapmap-snps.pruned.bim
Input_Binary_File=clean-Z-chr8.hapmap-snps.pruned.bed
Input_Untyped_Ped_Option=2
Input_Do_Error_Sim=no
Output_Path=.
AlleleFreq_SquaredDev=999999999.000000
PLINK=--bfile --missing-phenotype -9 --trait default
Analysis_Option=Merlin format
Count_Genotypes=4
Count_Halftypes=no

During output I receive the following errors:

WARNING: calloc allocating no memory at line 761 of file makeped1.c
WARNING: my_calloc called with nelem=0 elsize=4
ERROR: Pedigree 3769 has disconnected individuals (1st one with id 1)
ERROR: For the analysis type specified, a genetic map is required, but none are available in the map file.

I am not sure if this is a memory error, program bug or that I am really missing something in the map file. Can anybody point me in the right direction?

Hi, Arija were you able to find a way around the Error related to "Pedigree 3769 has disconnected individuals". I am also trying to convert to Merlin format from Plink and getting the same error!
