As such, you need to get access to the illumina sequences from another source, and create an appropriate adapter FASTA.\n+\n+To make this fasta, you must first understand how it will be used. Trimmomatic uses two strategies for adapter trimming: Palindrome and Simple\n+\n+With \'simple\' trimming, each adapter sequence is tested against the reads, and if a sufficiently accurate match is detected, the read is clipped appropriately.\n+\n+\'Palindrome\' trimming is specifically designed for the case of \'reading through\' a short fragment into the adapter sequence on the other end. In this approach, the appropriate adapter sequences are \'in silico ligated\' onto the start of the reads, and the combined adapter+read sequences, forward and reverse are aligned. If they align in a manner which indicates \'read-through\', the forward read is clipped and the reverse read dropped (since it contains no new data).\n+\n+Naming of the sequences indicates how they should be used. For \'Palindrome\' clipping, the sequence names should both start with \'Prefix\', and end in \'/1\' for the forward adapter and \'/2\' for the reverse adapter.All other sequences are checked using \'simple\' mode. Sequences with names ending in \'/1\' or \'/2\' will be checked only against the forward or reverse read. All other sequences will be checked against both the forward and reverse read. If you want to check for the reverse-complement of a specific sequence, you need to specifically include the reverse-complemented form of the sequence as well, with another name.\n+\n+The thresholds used are a simplified log-likelihood approach. Each matching base adds just over 0.6, while each mismatch reduces the alignment score by Q/10. Therefore, a perfect match of a 20 base sequence will score just over 12, while 25 bases are needed to score 15. As such we recommend values between 12 - 15 for this parameter. For palindromic matches, the entire read sequence plus (partial) adapter sequences can be used - therefore this threshold can be higher, in the range of 30-40. The \'seed mismatch\' parameter is used to make alignments more efficient, specifying the maximum base mismatch count in the \'seed\' (16 bases). Typical values here are 1 or 2.\n+\n+**Citation**\n+\n+Lohse M, Bolger AM, Nagel A, Fernie AR, Lunn JE, Stitt M, Usadel B.
