Hi, I have illumina ChipSeq data in txt format with this structure: @HWI-EAS225:8:1:1:58#0/1 NAGAGTGCCCGGGTTCAGTTCTCAGCACCCATGTGG +HWI-EAS225:8:1:1:58#0/1 DMSSSSSSUSSTTTUTSSSSSSSSSRQRTTTSSSUS @HWI-EAS225:8:1:1:1803#0/1 NCCATGGGAAGAGCTGGGCAGGCGGGCCGAGCGAAG +HWI-EAS225:8:1:1:1803#0/1 DLSTTSKOUTRRTTSSSTTTTSRPNNTOJOTSSRTB @HWI-EAS225:8:1:1:1547#0/1 NAGGGAAAAGTGGGACTGGCACTTGCCTCTACCAGC +HWI-EAS225:8:1:1:1547#0/1 DLVVVTPTVVVVUVVWVVUVVUWVVVWWWWWWWVVV Can I convert into Fastq format?If so, how can I? Furthermore, after using Map with Bowtie for Illumina, how can I use MACS (Model-based Analysis of ChIP-Seq) if I have two files for IP samples and two files for Control samples? Thank you so much.
