format of fix file in hMETIS

I am working on a project where I need to use hMETIS for partitioning. I am using hmetis-1.5.3-WIN32 .
I need some vertices to be in particular partitions. From manual it is clear that we can do this by using a fix file,
but the format of the fix file is not clear.
e.g. I have the test.hgr input file (with 7 vertices and 4 hyper edges) as -
====================
4 7
1 2
1 7 5 6
5 6 4
2 3 4
====================
By the manual what I can interpret is- the format of fix file should be as follows -
(if I want vertex 1 to be in partition 0 and vertex 7 to be in partition 1)
(fix.txt )
===============
1 0
2 -1
3 -1
4 -1
5 -1
6 -1
7 1
===============

Now if I want 4 partitions , I am giving the command - hmetis test.hgr fix.txt 4 5 10 1 1 3 0 24
When I am running this , I am getting the error - The file fix.txt contains more than 4 set of pre-assigned vertices.
Can anyone please tell me the format of the fix file and where am I going wrong?

RE: The first column of the fix

The first column of the fix file should not be provided. It should simply be:
0
-1
-1
-1
-1
-1
1
