Thanks! I have removed the white spaces. I am actually a beginner in Perl so kindly bear with me. However I have one doubt, could it be because of the usage of the redirection operator used in the usage of the perl script? Kindly let me know. Regards.

Hi Jayant,

Hi,

I am trying to upload a Perl script into Galaxy however it gives me an error "TypeError: 'NoneType' object does not support item assignment". It seems that there is a mismatch between the input and output arguments and the file formats specified. I would really be thankful if someone can help me with this. Thanks in advance. Attached is the perl script, the configuration file for the perl script and the global tool_conf.xml file.

Could you please consider to remove the white-space from your tool
configuration file methylation-snp.xml

for ex:
<command interpreter="perl">allsnp_modified.pl $input $output</command>
<data name="output" format="gff3" /> etc.

HTH, Vipin
