Dear @Dibakar

thank you for comment. But I need help regarding how to create files with .map extension. The website you suggested don't have such information.

Dear Qasim,

You can create just .txt file (in Notepad) with locus name ant its position in cM. Like:

Chr1

locus_1 3.052966

locus_2 10.208689

etc.

and then save it as a file with .map extension, that can be opened in MapInspect.

Best wishes,

Maria

Dear @Maria,

Many thanks for your help. It worked for me and saved plenty of time.

However, the method requires following modifications.

; Thu, 21 may 2020, 00:01 (Day, Date, Time)

; ngrp=1A (chromosome name), nloc=13 (no. of locus/genes)

Locus/Gene Name Position

TaMADS1 2.01

TaMADS2 4.97

In addition, one can add star and end positions of chromosomes to show full chromosomal lengths along with locus/gene name and positions.

Hopefully, it will help others.
