Differential expression analysis error

[link01153113]

the issue for the differential expression error is the first column naming. For example, there are a few study (experiments)'s experiment_short_title having invalid sign like below:

{
        "_index": "study",
        "_id": "PsOHhI0B-tReATpm7Ohe",
        "_score": 1,
        "_source": {

          ],
          "sample_description_comment": "SMSL saliva from a healthy control was collected while the orifice of the parotid duct was blocked by Lashley cups.",

          "search_engine": "",
          "sample_name": "Healthy Control"
        }
      },

The "#" sign:

{
        "_index": "study",
        "_id": "t8OHhI0B-tReATpm4uZ7",
        "_score": 1,
        "_source": {
          "contact_name": "Yanbao Yu",

          "sequence_mapped_swiss_count": "0",

          "bto_term_list": [
            "Saliva"
          ],
          "experiment_protein_count": "483",
          "Study_name": "Self-assembled STrap for global proteomics and salivary biomarker discovery.",
          "reference_line": "1009",
          "bto_ac": [
            "BTO:0001202"
          ],
          "sample_description_comment": "",
          "experiment_created_date": "2019-09-25 17:29:11",
          "experiment_group_id": 1009,
          "PubMed_ID": "30848925",
          "experiment_short_title": "_1DLC092118QE_Saliva_Strap_#7_run1",
          "Taxononomy_ID": "9606",
          "search_engine": "Proteome Discoverer version 2.3 / Sequest",
          "sample_name": "1DLC092118QE_Saliva_Strap_#7_run1"
        }
      },

And in the inputdata, it's using experiment_short_title as the experiment identifiers. R script does not allow those character.
In addition, there are 3 records having the same experiment_short_title: Walz et al. ‎2006

Might need to make sure experiments title and short title are unique based on study and experiments
There are lots of duplicated experiment_title in the index:
There are 206 records with the same experiment_title of "Association of salivary proteins with age, sex, body mass index, smoking and education"
There are 100 records with the same experiment_title of "Persistent Dysfunction of Innate Immune and Clotting Factors Detected in Saliva and Blood Plasma after COVID-19"
There are 36 records with the same experiment_title of "Mapping differences in salivary gland secretions using dried saliva spots"
There are 30 records with the same experiment_title of "Self-Assembled STrap for Global Proteomics and Salivary Biomarker Discovery"
There are 3 records with the same experiment_title of "Proteome analysis of glandular parotid and submandibular-sublingual saliva in comparison to whole human saliva by two-dimensional gel electrophoresis"

For experiment_short_title, there are 3 records having the same experiment_short_title. This one is easy to fix.
