Single end RNAseq- no BAM file generated

[ibn.adam]

Dear all,

I am mapping one end mRNA sequencing on TOPHAT with human reference genome hg19.

It looks like script worked partially and It has generated .BAM file of 7 million MB. But geneexpression.txt are empty.

Here is the error file:

please help me in correcting the script.
