Hello Lemur Team,

I posted a problem i was facing about a week ago on an error i am getting trying to use DistRetEval. I have realized that, this same question had been asked a number of times but no answers or solution was given. I have read and done everything possible to resolve this problem , but no avail. Below is my parameter file for the DistRetEval , everything thing else works fine

<parameters>
<index>/home/ubuntu/Ghansah/dfIndex.key</index>
<collCounts>/home/ubuntu/Ghansah/dfCounts</collCounts>
<textQuery>/home/ubuntu/Ghansah/let.txt</textQuery>
<ranksFile>/home/ubuntu/Ghansah/Ret_Rank/rank.txt</ranksFile>
<resultFile>/home/ubuntu/Ghansah/Ret_Result/result.txt</resultFile>
<mergeMethod>0</mergeMethod>
<database1>/home/ubuntu/Ghansah/db1.txt</database1>
<database2>/home/ubuntu/Ghansah/db2.txt</database2>
<cutoff>5</cutoff>
<resultCount>60</resultCount>
</parameters>

and the db parameter files are

<parameters>
<index>/home/ubuntu/Ghansah/one-index/one-index.key</index>
<retModel>inquery</retModel>
</parameters>

<parameters>
<index>/home/ubuntu/Ghansah/two-index/two-index.key</index>
<retModel>inquery</retModel>
</parameters>

The error message is
